  • Your Data Is Collected and Chapter Four Is Blank (2026)

    Your Data Is Collected and Chapter Four Is Blank (2026)

    The questionnaires came back three weeks ago. They are in a bag under your bed, or encoded into a spreadsheet you have not opened since. Chapters One, Two and Three are done and approved. Chapter Four is a heading and a blinking cursor, and the defence date has not moved.

    This is the most common place a Nigerian final year project stalls, and it is worth understanding why, because the reason is not laziness and it is not that you do not know statistics.

    Why Chapter Four freezes people when Chapters One to Three did not

    Chapters One, Two and Three are chapters about intentions. You state a problem you intend to solve, review literature you intend to build on, and describe a method you intend to follow. All of it can be written from decisions you already made, and none of it can be checked against anything external. If a sentence is weak, it is weak in a way that reads as style.

    Chapter Four is the first chapter where you can be wrong in a way that anybody can check. A percentage that does not sum. A mean that contradicts the table above it. A chi-square value nobody can reproduce. A respondent count that reads 231 here and 236 there. All of it is arithmetic, and arithmetic is either right or it is not.

    That is what the blank page is about. It is not writer’s block. It is the reasonable fear of committing a checkable claim to paper — and the fear grows every day you avoid it, because the deadline shrinks while the task stays the same size.

    The unlock: you are not writing a chapter

    You are writing one table, four times.

    A Nigerian Chapter Four is not a piece of continuous prose. It is a repeating unit: a research question, the table that answers it, and a paragraph underneath. Then the same unit again. Then again. Then the hypotheses, which are their own short unit.

    That matters because a repeating unit is enormously easier to start than a chapter. You do not need to know how Chapter Four ends before you write its first paragraph. You need to know what your first research question is and which table answers it — and you decided both of those in Chapter One.

    Write the research questions on four sticky notes, in order, and put the name of the answering table under each. That is your chapter outline, and it took four minutes.

    Sticky notes laid out in a row, each carrying one research question and the table that answers it
    Four minutes with sticky notes turns “write Chapter Four” into four separate small jobs, each of which you know how to do.

    The four-evening plan

    1. Evening one: encode and screen. Number the questionnaires, build the variable list, enter the data, then run frequencies and check every minimum and maximum. Write nothing. The full order of operations is in the guide to analysing project data in SPSS step by step.
    2. Evening two: produce the tables. The bio-data table, then one mean table per research question, then the test for each hypothesis. Which test belongs to which question is settled in choosing the statistical test for your project. Still write no prose.
    3. Evening three: the paragraphs. One under each table, three sentences minimum. This is the slowest evening and it deserves your best hours.
    4. Evening four: reconcile. One respondent count everywhere including the abstract, every table numbered and referred to in the text, every hypothesis carrying a stated decision.

    Four evenings is a realistic figure for a straightforward undergraduate project, and it is achievable precisely because the first two evenings involve no writing at all. Most of the paralysis comes from trying to do all four at once.

    The three sentences that unblock any table

    When you reach evening three and the paragraph will not come, the problem is almost always that you are trying to write something interesting. Do not. Write these three sentences, in this order:

    1. What the table shows. “Table 2 shows a grand mean of 2.85 against a criterion mean of 2.50, indicating general agreement.”
    2. What that means here. “This suggests the constraint is felt most acutely in the evenings, consistent with the reliance on alternative power sources reported in item 2.”
    3. How it compares. “Adeyemi (2023) reported a similar pattern among undergraduates in a comparable state university.”

    That is a complete, defensible interpretation paragraph. It is not elegant and it does not need to be. Do it four times and Chapter Four exists. The full pattern, with worked Nigerian tables, is in the guide to writing Chapter Four.

    Sentence three is the one students skip, and skipping it is why supervisors write “no discussion” in the margin — the same correction loop described in breaking the Chapter Two correction loop, arriving two chapters later.

    Tables first, prose second. Nobody writes a good interpretation of a table they have not built.

    What an AI project writer can and cannot do here

    Worth being precise about, because the honest boundary is narrower than the advertising and the temptation peaks at exactly the point in the calendar you are probably at now.

    It cannot produce your numbers. Your means, your percentages and your chi-square value come from your data file and nowhere else. Anything that hands you statistics you did not compute is handing you a problem you will meet again at the defence, when a panel member asks which software produced them and on how many respondents. There is no recovery from not knowing where your own numbers came from.

    It cannot write sentence two. Why your lowest-rated item is lowest depends on your department, your campus, your local government area and your respondents. That is the sentence a panel probes hardest, and it is the one only you can write.

    It cannot pick your comparison study. Sentence three has to name a study that is actually in your Chapter Two and that you have actually read. A citation that does not resolve is worse than no citation, and it puts every other reference in your chapter in doubt.

    What it is genuinely good at is structure and consistency — holding the chapter in the shape your department expects, keeping each citation attached to the source you actually opened, and making sure the respondent count and the tool names stay identical everywhere they appear. That is the mechanical work that is easy to get wrong at midnight and tedious to check by hand, and it is most of what stands between a finished analysis and a submitted chapter.

    And the thing not to do

    Do not buy a written Chapter Four. Beyond the integrity problem, it fails on its own terms: a purchased chapter analyses data that is not yours, so its numbers will not match your Chapter Three, its respondent count will not match your instrument, and you will not be able to answer a single question about it. What you are actually buying is examined in project topics and materials in Nigeria: what you are actually buying.

    You have the data. That is the part that could not be rushed, and it is done. What remains is four evenings of ordinary, structured work.

    The data is yours. Get the chapter out of your head and onto the page.

    Tesify holds your chapters in the structure your department expects and keeps every citation attached to a source you actually opened, so your respondent count stays consistent across Chapters Three, Four and the abstract while you write. Over 9,000 students have used it to write more than 15,000 chapters, and every word is still written by you.

    Frequently asked questions

    How do I start writing Chapter Four when I do not know where to begin?

    Write your research questions on separate notes in order and name the table that answers each. That is your outline. Then build all the tables before writing any prose, and write one three-sentence paragraph under each.

    How long should Chapter Four take?

    About four evenings for a straightforward undergraduate project: one to encode and screen, one to produce the tables, one for the interpretation paragraphs and one to reconcile. It takes far longer if you try to do all four at once.

    Why can I write Chapters One to Three but not Chapter Four?

    Because the first three are about intentions and cannot be checked against anything external, while Chapter Four commits arithmetic that anybody can verify. The hesitation is rational; the fix is to break it into one table at a time.

    Can an AI write my Chapter Four for me?

    It should not, and the parts that matter it cannot. Your numbers come from your data file, the interpretation depends on your setting, and the comparison must name a study from your own Chapter Two. Use a tool for structure and consistency and write the substance yourself.

    What if my analysis shows nothing significant?

    Report it. A non-significant result is a finding, not a failure, and it is entirely defensible when your method was sound. What is not defensible is adjusting the data until something turns significant.

    Do I need to have finished the analysis before writing anything?

    You need the tables finished before writing the paragraphs about them, but you can write the chapter’s opening paragraph — the return rate and what the chapter contains — as soon as you know your final respondent count.

    My supervisor is not responding. Should I wait?

    No. Build the tables and draft the paragraphs, then send a complete draft. A supervisor with something concrete in front of them responds faster than one asked an open question, and you lose nothing if a table has to change.

    What if I lost some questionnaires?

    Report the three counts honestly — administered, retrieved, usable — and let the return rate be whatever it is. A disclosed shortfall is a limitation; a concealed one is a defect a panel finds by adding up your table.

    Is it too late if my defence is in two weeks?

    No, if your data is collected. Four evenings of structured work produces a defensible Chapter Four, and Chapter Five is written from Chapter Four without adding anything new. Start with the encoding tonight.

    Should I write Chapter Five before or after Chapter Four?

    After, always. Chapter Five summarises what Chapter Four found. Writing it first means writing conclusions from expectations rather than from data, and a panel can tell.

  • How to Analyse Your Project Data in SPSS, Step by Step (2026)

    How to Analyse Your Project Data in SPSS, Step by Step (2026)

    The questionnaires are back. There are two hundred and thirty of them in a nylon bag, SPSS is open on a borrowed laptop, and the cursor is blinking in an empty grid. This is where most Nigerian project groups lose a week — not to the statistics, which are usually simple, but to not knowing the order of operations.

    What follows is that order, in nine steps, with the exact menu path for every procedure an undergraduate project needs. Paths are quoted as documented in Kent State University Libraries’ freely available SPSS tutorials; recent versions keep them stable, but if a menu on your machine reads slightly differently, trust your machine.

    Two things belong upstream of this guide. You should already know which tool answers which research question — that decision is made in choosing the statistical test for your project, not in the software. And what you do with the output afterwards is a separate skill, set out in writing Chapter Four.

    Step 1: Number the questionnaires before you touch a computer

    Output: a physical stack in which every usable copy carries a unique case number.

    1. Separate the incomplete copies into their own pile. Count both piles and write both counts down; your return rate needs them.
    2. Write 1, 2, 3 in the top corner of each usable questionnaire.
    3. Keep the stack in that order for the whole encoding session.

    This takes fifteen minutes and it is the only thing that makes an encoding error recoverable. When SPSS later shows a respondent aged 220, the case number tells you which sheet of paper to check. Without it you are re-reading 231 questionnaires to find one typo.

    A stack of questionnaires with case numbers handwritten in the top corner of each
    Fifteen minutes with a pen. This is what turns “there is an error somewhere” into “the error is on copy 147”.

    Step 2: Build the variable list before entering a single response

    Output: a complete Variable View, filled in before any data exists.

    Click the Variable View tab at the bottom of the data editor. Every questionnaire item becomes one row, and four columns matter.

    • Name — short, no spaces, systematic. Use sex, level, dept, then B1 to B10 and C1 to C10 so the names mirror the sections of your instrument.
    • Label — the full item text. This is what prints on your output tables, so a good label here saves retyping every row of Chapter Four by hand.
    • Values — the numeric code for each option: 1 = Strongly Disagree through 4 = Strongly Agree, or 1 = Male, 2 = Female.
    • Measure — Nominal for categories such as sex or department, Ordinal for Likert items, Scale for genuinely continuous variables such as age or a computed total.

    Getting Measure right early prevents a whole class of later confusion, because SPSS uses it to decide which procedures it offers you for a variable.

    A handwritten codebook page mapping questionnaire answer options to numeric codes
    Agree the codebook on paper first. If three of you are encoding on three laptops, this page is the only thing that makes the files mergeable.

    Step 3: Encode the responses, one row per respondent

    Output: a Data View grid with as many rows as you have usable questionnaires.

    Switch to Data View and work down the numbered stack. One respondent is one row; one item is one column. Never put two respondents on one row and never spread one respondent across two.

    Three rules prevent the expensive mistakes. Leave a genuinely unanswered item blank rather than typing 0 — zero is a real value and it will drag your mean down. Decide as a group how to treat an item where a respondent ticked two boxes, then apply that decision to every case rather than case by case. And if you split encoding across several laptops, agree the codebook in writing first, because merging three files that coded sex differently costs more than the encoding did.

    Save as a .sav file after every fifty cases, with the date in the filename.

    Step 4: Reverse-score the negatively worded items

    Output: new variables in which every item points the same direction.

    If your instrument contains an item like “Power supply has no effect on how long I study”, a high score there means the opposite of a high score on the rest of the scale. Averaging it in unreversed will depress your grand mean and wreck your reliability coefficient.

    1. Go to Transform > Recode into Different Variables.
    2. Move the negatively worded item across and give the output variable a new name, such as B7r.
    3. Click Old and New Values and enter the reversal for a four-point scale: 1→4, 2→3, 3→2, 4→1.
    4. Click Add for each pair, then Continue and OK.

    Always recode into a different variable, never over the original. Keeping the raw column means a mistake here is one recode away from being fixed rather than a re-encoding away.

    Step 5: Screen the data before you analyse it

    Output: a frequency table for every variable, checked against the range each is allowed to take.

    Run Analyze > Descriptive Statistics > Frequencies, move all your variables across, and read the output for three things.

    • Impossible values. A four-point item with a maximum of 5 is a typo. Find the case number and check the paper.
    • Missing counts. Every variable’s Valid N should equal your analysed N unless you know why it does not.
    • Category totals. The frequencies for sex should sum to your N. If they do not, a case is miscoded.

    Fix everything you find here before running anything else. An error corrected now costs a minute; the same error found after three tables are written costs the afternoon.

    Step 6: Run the reliability analysis

    Output: a Cronbach’s alpha for each section of your instrument.

    1. Go to Analyze > Scale > Reliability Analysis.
    2. Move in the items of one section only — Section B on its own, then Section C on its own. A scale measuring two different constructs is not one scale.
    3. Leave the Model on Alpha.
    4. Click Statistics and tick Item, Scale, and Scale if item deleted.
    5. Read the alpha, then read the “Cronbach’s Alpha if Item Deleted” column to see whether one bad item is dragging the section down.

    Report the coefficient with the number of items and the pilot sample it came from, in Chapter Three. You will be asked at the defence which software produced it, so do not report a figure you did not compute.

    Step 7: Produce the descriptive tables Chapter Four needs

    Output: the bio-data table and the per-item mean tables, in that order.

    For the respondent profile — sex, level, department — use Analyze > Descriptive Statistics > Frequencies and take the frequency and percentage columns straight into your table.

    For the “level of” or “extent of” research questions, use Analyze > Descriptive Statistics > Descriptives with the Likert items of that section selected; the Mean and Std. Deviation columns are exactly what your table needs. For the grand mean, build a computed variable first with Transform > Compute Variable using the MEAN function across the items of that section.

    Compare each mean against your criterion mean — 2.50 on a four-point scale — and fill the Decision column accordingly.

    Step 8: Run the inferential test each hypothesis needs

    Output: one output block per hypothesis, and no blocks you cannot attach to a hypothesis.

    What your hypothesis asks Procedure Menu path
    Are two categorical variables associated? Chi-square test of independence Analyze > Descriptive Statistics > Crosstabs, then Statistics > Chi-square
    Are two scale variables related? Pearson correlation Analyze > Correlate > Bivariate
    Are two ordinal or non-normal variables related? Spearman’s rho Analyze > Correlate > Bivariate, tick Spearman
    Do two groups differ? Independent-samples t test Analyze > Compare Means and Proportions > Independent-Samples T Test
    Do three or more groups differ? One-way ANOVA Analyze > Compare Means > One-Way ANOVA
    Is the distribution normal? Shapiro-Wilk and Kolmogorov-Smirnov Analyze > Descriptive Statistics > Explore, then Plots > Normality plots with tests

    Three details the dialogs will force on you. In Crosstabs the chi-square statistic is not produced unless you tick it under Statistics — the crosstab alone is only a contingency table, and this is the single most common reason a Nigerian student cannot find their chi-square value. In Bivariate, Pearson is selected by default and the test is two-tailed by default, with significance flagged at the .05 and .01 levels. And the Independent-Samples T Test will not run until you click Define Groups and specify the two codes being compared.

    Step 9: Save the output and reconcile it before writing

    1. Save the data as .sav and the output as .spv, both dated, and copy both to a second device or a cloud folder.
    2. Check that the Valid N on your output matches the analysed N you stated in Chapter Three.
    3. Check that every research question and hypothesis has exactly one output block, and delete the exploratory runs you did along the way.
    4. Check that the tools that produced your output are the ones you named in Chapter Three. If you changed one, change the chapter too.

    Only then start writing. A Chapter Four built from unreconciled output will contradict Chapter Three somewhere, and that contradiction is the first thing a panel finds — as the standard question list in what is asked during a project defence makes clear. How the analysis chapter sits within the whole document is summarised in how many chapters a final year project has.

    You have the output. Now write the chapter.

    Tesify holds your chapters in the structure your department expects and keeps every citation attached to a source you actually opened, so the week after analysis goes into interpretation rather than formatting. Over 9,000 students have used it to write more than 15,000 chapters, and every word is still written by you.

    Frequently asked questions

    How do I analyse my project data using SPSS?

    Number the questionnaires, build the full Variable View before entering data, encode one row per respondent, reverse-score the negative items, then screen with Frequencies. Only after screening do you run reliability, descriptives and your inferential tests.

    What is the menu path for Cronbach’s alpha?

    Analyze > Scale > Reliability Analysis, with the Model left on Alpha. Enter one section at a time and tick “Scale if item deleted” under Statistics to see which item is weakening it.

    Why is my chi-square value not showing?

    Because it is not produced by default. Open the Statistics button inside the Crosstabs dialog, tick Chi-square, then run it again.

    How do I encode a four-point Likert scale?

    Set the item’s Measure to Ordinal and define its Values as 1 to 4 with the verbal label attached to each number. Then type only the numbers into Data View.

    Should I enter 0 for an unanswered item?

    No. Leave it blank. Zero is a real value on a numeric variable and it will pull the mean down and misstate the count of valid responses.

    Do I have to reverse-score negative items?

    Yes, if you are averaging items into a section score or computing a reliability coefficient. Skipping it is the commonest cause of an unexpectedly low Cronbach’s alpha in an otherwise sound instrument.

    How do I get the grand mean in SPSS?

    Build the section score first with Transform > Compute Variable using the MEAN function across that section’s items, then run Descriptives on the new variable.

    Which SPSS version do I need?

    Any recent version handles everything an undergraduate project needs. Menu wording shifts slightly between releases, so state in Chapter Three the version you actually used rather than copying a number from another project.

    My groupmates encoded on separate laptops and the files will not merge. What now?

    Compare the Variable View of each file side by side before merging. Mismatched variable names, different codes for the same answer and different Measure settings are the usual culprits, and all three are fixable in the file that deviates rather than by re-encoding.

    Do I keep the output file after the defence?

    Keep it until your project is finally approved and bound. Panels ask to see output, corrections can require reruns, and rebuilding a lost analysis from paper questionnaires under deadline is a miserable weekend.

    Can I do all of this without SPSS?

    Yes. Free packages cover the same undergraduate procedures, and spreadsheets handle means and percentages. Whichever you use, name that one in Chapter Three rather than naming SPSS by habit.

  • How to Write Chapter Four of a Final Year Project in Nigeria: Data Presentation, Analysis and Interpretation (2026)

    How to Write Chapter Four of a Final Year Project in Nigeria: Data Presentation, Analysis and Interpretation (2026)

    Chapter Four is where a final year project stops being reading and starts being evidence. Most Nigerian departments title it Data Presentation, Analysis and Interpretation, and most students write it the same wrong way: they collect the questionnaires, run everything they can think of, paste the output in, and then try to build sentences around whatever appeared.

    The chapter is written one table at a time, in the order of your research questions, and nothing that answers no research question belongs in it. What follows is that procedure in eight steps, with the actual tables and sentences you will need.

    One thing outranks everything below: your department’s project guidelines. Departments at UNILAG, Ibadan, ABU Zaria, OAU and Nsukka differ on table numbering, on whether hypotheses are tested inside Chapter Four or Chapter Five, and on whether a decision rule must be stated in words. Where this guide and your handout disagree, follow the handout.

    Step 1: Rebuild the chapter outline from your research questions

    Output: a numbered sub-section list matching your Chapter One, written before you open any data.

    1. Open Chapter One and copy out the research questions in order, exactly as worded.
    2. Give each one its own sub-heading in Chapter Four, in the same order.
    3. Beside each, note the single table that will answer it.
    4. Add one sub-section per hypothesis, after the research questions.
    5. Delete every piece of output not assigned to a heading.

    Four research questions means four tables plus one per hypothesis. If you have eleven tables, several of them are answering nothing, and a panel member will ask why you ran them. The alignment between what you asked and what you answer is the thing being examined — the same alignment described in the guide to writing Chapter One.

    Step 2: Fix the return rate, and never change the number again

    Output: three counts, and one of them used everywhere afterwards.

    Chapter Four opens by saying how many questionnaires went out, how many came back, and how many were usable. Write it once, plainly:

    “A total of 250 copies of the questionnaire were administered to respondents in the five departments studied. Of these, 236 copies were retrieved and 231 were properly completed and used for the analysis, giving a return rate of 92.4%. The analysis in this chapter is therefore based on 231 respondents.”

    That last number is the one that appears in every table note, in the abstract, and in any percentage you compute. A respondent count that reads 231 in one table and 236 in another is the single most commonly caught defect in Nigerian project defences, and it costs you credibility on every other figure in the chapter. How you arrived at those counts belongs in Chapter Three, not here.

    Step 3: Present the bio-data as a frequency and percentage table

    Output: one table covering the respondent profile, and one short paragraph under it.

    The demographic section is descriptive only. It uses frequency and simple percentage, nothing else.

    Table 1: Distribution of Respondents by Demographic Characteristics

    Variable Category Frequency Percentage (%)
    Sex Male 128 55.4
    Female 103 44.6
    Level 300 Level 74 32.0
    400 Level 92 39.8
    500 Level 65 28.2
    Age Below 25 years 167 72.3
    25 years and above 64 27.7

    Source: Field Survey, 2026. n = 231.

    Two rules. Every block of percentages sums to 100 against your N, so check the arithmetic before the panel does. And keep the paragraph underneath short — the bio-data is context, not a finding, and a page of prose about how many respondents were male tells the reader nothing they cannot see.

    A printed frequency and percentage table with a handwritten interpretation in the margin
    One table, one finding, one paragraph. If you cannot underline the row your paragraph is about, the paragraph is not about anything.

    Step 4: Build the mean table for each research question

    Output: one table per research question, with mean, standard deviation and a decision column.

    Most Nigerian undergraduate instruments use a four-point scale: Strongly Agree 4, Agree 3, Disagree 2, Strongly Disagree 1. The criterion mean is 2.50, because the four scale points average to 2.50 — an item at or above it is Accepted, below it is Rejected. If your department uses a five-point scale, the criterion is 3.00 by the same arithmetic. State whichever you used, and where it came from, in the note under the table.

    Table 2: Effect of Power Supply on Student Study Hours

    S/N Item Mean SD Decision
    1 Irregular power supply reduces my evening study hours 3.42 0.71 Accepted
    2 I rely on a generator or power bank to study at night 3.18 0.84 Accepted
    3 I use the departmental reading room when there is no light at home 2.87 0.92 Accepted
    4 Power supply has no effect on how long I study 1.94 0.88 Rejected
    Grand Mean 2.85 0.84 Accepted

    Source: Field Survey, 2026. n = 231. Criterion mean = 2.50.

    Carry the standard deviation next to every mean. A mean of 3.42 with an SD of 0.71 describes a group that broadly agrees; the same mean with an SD of 1.40 describes a group that is split, and a panel may well ask which one you have. Item 4 above is reverse-worded on purpose — note that it was rejected, which is consistent with the other three rather than contradicting them.

    Step 5: Write the interpretation paragraph, in three moves

    Output: one paragraph under each table that does not simply retype the table.

    If your prose reads “from Table 2 above, item 1 has a mean of 3.42, item 2 has a mean of 3.18, item 3 has a mean of 2.87”, you have transcribed the table and said nothing. Every paragraph needs three moves:

    1. State the finding. The highest and lowest items and the overall picture, in one sentence.
    2. Say what it means in your setting — your department, your campus, your respondents.
    3. Connect it to Chapter Two. One named study your finding agrees or disagrees with.

    Worked paragraph:

    “Table 2 shows a grand mean of 2.85 against a criterion mean of 2.50, indicating that respondents generally agree that power supply affects their study hours. The strongest agreement was on the reduction of evening study hours (M = 3.42, SD = 0.71), while the claim that power supply has no effect was rejected (M = 1.94, SD = 0.88). This suggests that the constraint is felt most acutely at night, which is consistent with the reliance on generators and power banks reported in item 2, and with the departmental reading room serving as the fallback rather than the first choice. Adeyemi (2023) reported a similar pattern among undergraduates in a comparable state university, although the reliance on alternative power sources in the present study is higher.”

    The third move is the one almost always missing, and its absence is why a supervisor writes “no discussion” in the margin. The studies you compare against come from your literature review, and every author you name here must appear in your reference list in the style your department requires — the conventions are in the guide to referencing a Nigerian university project in APA.

    Step 6: Test each hypothesis and write the decision sentence

    Output: one sub-section per hypothesis, each ending in an explicit decision.

    Hypothesis sub-sections have a fixed shape, and panels test it because it is short enough to check line by line. State the hypothesis, present the table, state the decision.

    Worked example:

    Ho₁: There is no significant relationship between power supply and student study hours.

    “The chi-square test returned a calculated value of 18.42 with 4 degrees of freedom at the 0.05 level of significance, against a critical table value of 9.488. Since the calculated value (18.42) is greater than the critical value (9.488), the null hypothesis is rejected. There is therefore a significant relationship between power supply and student study hours.”

    Many Nigerian departments still teach the calculated-versus-critical-value comparison, while statistical software reports a p-value instead. The two agree: a calculated value above the critical value corresponds to a p-value below 0.05. If your output gives you p, the equivalent sentence is “χ²(4, N = 231) = 18.42, p = .001; the null hypothesis is rejected.” Use whichever form your department teaches, and use only one of them throughout the chapter.

    Two wordings a panel will correct on the spot. You reject or fail to reject a null hypothesis — you never accept it and you never prove it. And a significant result is not automatically a large or important one, so the sentence after the decision should say what the relationship means in practice.

    Take the tables to your supervisor before you write the prose. A wrong table costs an afternoon; a chapter written around a wrong table costs a week.

    Step 7: Report the numbers the way the style requires

    Output: one pass over every figure in the chapter.

    Nigerian departments overwhelmingly use APA, and its rules on numbers are narrower than most students realise. From the APA Style numbers and statistics guidance:

    1. Decimal places. Means and standard deviations from an integer scale — your four-point questionnaire — take one decimal in APA’s own convention, although many Nigerian departments require two. Follow your department, but be consistent across every table.
    2. Leading zeros. Include the zero before the decimal point only when the statistic can exceed 1. A correlation, a proportion and a p-value cannot, so write r = .42 and p = .03, not 0.42.
    3. Exact p values to two or three decimals, except below .001, where you write p < .001.
    4. Numerals for 10 and above and for every number used in a statistic; words for zero to nine and for any number that opens a sentence.
    5. Do not repeat a statistic in both the text and a table. Quote only the figures your argument turns on.
    6. Statistical symbols are italic — M, SD, r, p, N — and never need defining. ANOVA and CI do.

    Step 8: Reconcile before you submit

    1. Questions equal sub-sections. Four research questions, four sub-sections, same order, same wording.
    2. Tools equal tables. Every tool named in Chapter Three produces a table here, and no table comes from a tool you never named.
    3. One N everywhere. Chapter Three, every table note, and the abstract.
    4. Every table is mentioned by number in the text at least once.
    5. Every hypothesis has a decision stated in words, not just a table.

    Then run the spoken test: can you state each finding in one sentence without looking at the page? That is precisely what you will be asked to do, and the standard inventory of what else gets asked is in the guide to what questions are asked during a project defence. How the whole document fits together is summarised in how many chapters a final year project has.

    You have the data. Now build the chapter.

    Tesify holds your chapters in the structure your department expects and keeps every citation attached to a source you actually opened, so the week after data collection goes into interpretation instead of formatting. Over 9,000 students have used it to write more than 15,000 chapters, and every word is still written by you.

    Frequently asked questions

    How do I write chapter four of a project?

    Create one sub-section per research question, in the order they appear in Chapter One. Under each, place one table and a paragraph that states the finding, explains it in your setting and compares it with a study from Chapter Two. Then add one sub-section per hypothesis, each ending in an explicit decision.

    What is chapter four of a project called?

    Most Nigerian departments title it “Data Presentation, Analysis and Interpretation” or “Presentation and Analysis of Data”. Check your department’s project guidelines, because the exact wording is usually prescribed.

    What is the criterion mean for a four-point scale?

    2.50, being the average of 4, 3, 2 and 1. An item at or above 2.50 is accepted and one below it is rejected. On a five-point scale the criterion is 3.00.

    How many tables should chapter four have?

    Roughly one per research question, plus one per hypothesis, plus the bio-data table. Most Nigerian undergraduate projects land between five and nine. A chapter with fifteen tables usually means software output was pasted in rather than selected.

    Do I put the standard deviation in the table?

    Yes. The mean alone does not tell the reader whether respondents agreed with each other, and a panel can reasonably ask for the spread. Report it beside every mean.

    Should hypotheses be tested in chapter four or chapter five?

    Chapter Four in most Nigerian departments, with Chapter Five reserved for the summary, conclusion and recommendations. Some departments differ, so follow your handout.

    Can I say I accepted the null hypothesis?

    No. Say you failed to reject it, or that it was not rejected. Not finding evidence of a relationship is not evidence that no relationship exists, and this is corrected in almost every defence where it appears.

    What does the decision rule mean in hypothesis testing?

    It is the stated basis on which you accept or reject: either the calculated value against the critical table value at your degrees of freedom, or the p-value against 0.05. Both are valid; state which you used and use only that one throughout.

    Do I discuss my findings in chapter four or chapter five?

    Where your department says. Many Nigerian projects place a discussion of findings at the end of Chapter Four and keep Chapter Five for the summary and recommendations. What matters is that the discussion exists somewhere and compares your findings with the literature.

    What if my findings contradict the studies in chapter two?

    Report it plainly and explain it from your setting — a different population, a different period, a different instrument. A contradiction that is explained is a contribution; one that is quietly omitted is a defect a panel finds by reading your Chapter Two.

    Do recommendations go in chapter four?

    No. Chapter Four presents and interprets what the data showed. The moment you start telling the department what it should do, you have crossed into Chapter Five.
