Do I need statistics software for IB SEHS analysis?

No. In IB SEHS, what matters most is that your calculations are correct and your reasoning is transparent. Many students use Excel or Google Sheets because they can show formulas, tables, and steps clearly. The key is to avoid “black box” analysis where a number appears without explanation of what it represents. Whatever tool you use, label outputs and connect them back to your variables and hypothesis. If you’re unsure whether you’ve interpreted an output correctly, practice similar questions in the RevisionDojo Questionbank and compare your reasoning to the model solutions. Over time, you build a repeatable method instead of relying on luck.

What if my IB SEHS results are not statistically significant?

That can still score well, because non-significant results are still results. In IB SEHS, you earn marks by explaining what non-significance suggests: maybe the effect is small, your sample size is limited, or your data variability is high. You should also discuss practical significance: a change might matter in real sport even if p is above 0.05, depending on context. Most importantly, don’t force causation or pretend the hypothesis was “proven wrong.” Instead, evaluate limitations, propose improvements, and show you understand reliability and validity. RevisionDojo’s notes and flashcards help you use the right language so your evaluation reads like science, not disappointment.

How do I know whether to use a paired t-test, unpaired t-test, or correlation in IB SEHS?

Start with your design, not your data. In IB SEHS, a paired t-test fits repeated measures on the same participants, because you’re comparing each person to themselves. An unpaired t-test fits two separate groups, where participants differ between conditions. Correlation fits two continuous variables where you’re testing whether they move together, not whether one caused the other. Then check assumptions in a basic way: are your measurements numerical, and does the comparison match what you’re claiming? If you’re torn, use RevisionDojo’s topic resources and practice sets to see how exam questions frame each method, and use AI Chat to sanity-check your choice with your exact variables.

IB SEHS Data Analysis Like a Pro: Stats + Evaluation Tips

IB SEHS

• 19 Jul 2026•6

The night before a deadline, every spreadsheet starts to feel personal. The numbers aren’t just numbers anymore; they’re a verdict. And in IB SEHS, that pressure hits hardest when you have to analyze data, justify your statistics, and then evaluate your study like you meant to design it that way all along.

The good news: most students don’t lose marks because their data is “bad.” They lose marks because they don’t explain what their data means, why they used a method, and what their results do (and don’t) allow them to claim. That’s a skill you can train.

The IB SEHS data analysis checklist (use this every time)

Before you touch conclusions, run this quick loop:

Define your variables clearly (IV, DV, units, conditions).
Calculate descriptive statistics (mean, standard deviation, maybe coefficient of variation).
Choose the correct inferential test (paired t-test, unpaired t-test, or correlation).
Visualize the result (scatterplot or bar chart with error bars).
Interpret significance (often p ≤ 0.05) without overclaiming.
Evaluate limitations and improvements (validity, reliability, control of variables).

When you’re unsure, anchor your revision in RevisionDojo’s IB SEHS hubs and topic pathways so you’re practicing exactly what gets assessed: Sports, exercise and health science (SEHS) resources.

IB SEHS statistics: choosing tests that fit your design

In IB SEHS, the “right” test is mostly about your study design:

Paired vs unpaired t-tests

Use a paired t-test when the same participants do both conditions (pre/post, left/right, before/after fatigue). This controls individual differences.
Use an unpaired t-test when you compare two separate groups (trained vs untrained, male vs female, two teams).

If you need to tighten fundamentals (mean, SD, interpreting spread), RevisionDojo’s notes break it down cleanly: Calculate mean and standard deviation (6.1.2) and Standard deviation for comparing data sets.

Correlation (and the classic trap)

Correlation is for relationships between two continuous variables (e.g., VO₂ max and time trial performance). Report r and interpret strength and direction. If you include r², explain it as “variance explained,” not “proof.”

A fast way to harden your instincts is to drill exam-style items in the RevisionDojo Questionbank and read solutions like a coach reads game film: SEHS Anatomy questionbank and SEHS Skill in Sport questionbank.

Presenting IB SEHS data clearly (so markers trust you)

Clean reporting is quiet persuasion. In IB SEHS, aim for:

Mean ± SD for each condition (with units every time).
Graphs that match the question:
- Scatterplot for correlations.
- Bar chart with error bars for condition comparisons.
Axes labeled with variable name and unit.

To build speed, use RevisionDojo Flashcards for definitions and thresholds (p-value, validity, reliability), then test immediately: IB Flashcards with spaced repetition.

Evaluation tips that score: interpret like a scientist, not a fan

Evaluation is where you prove maturity. Try this structure:

What happened? Summarize the pattern (increase/decrease/no change).
What does it suggest? Link to SEHS theory (energy systems, biomechanics, physiology).
What can’t you claim? Especially if results are non-significant or confounded.
Why might this have happened? Measurement error, sample size, uncontrolled variables.
How would you improve it? Specific upgrades: tighter protocol, calibrated equipment, more trials, better randomization.

Using RevisionDojo to train IB SEHS analysis for exams

A simple routine that works:

Learn the concept in Study Notes (one small chunk).
Lock vocabulary with Flashcards.
Apply in the Questionbank with mixed questions.
Use AI Chat when your reasoning is shaky (ask it to challenge your conclusion).
Use Grading tools to see if your explanation would actually earn marks.
Add Predicted Papers and Mock Exams as you get closer to exams for timing and stamina.

For realistic exam rehearsal, explore: SEHS Papers and the broader collection: IB Predicted Papers.

Final takeaway: make IB SEHS data feel inevitable

The best IB SEHS analysis feels calm because it’s methodical: you choose a test that matches your design, present data so a stranger can follow it, and evaluate results with honesty. That’s exactly what RevisionDojo is built to train, with Study Notes, Flashcards, a Questionbank, AI Chat, Grading tools, Predicted Papers, Mock Exams, a Coursework Library, and Tutors to push you from “I did stats” to “I can defend my stats.”

If you want one action step today, open the IB SEHS hub, pick one stats-related subtopic, and run the loop: notes, flashcards, question practice. Consistency beats cramming, especially when your spreadsheet starts feeling personal again.
