How detailed should my IB SEHS data section be?

Your IB SEHS data section should be detailed enough that your results feel earned, not guessed. That means raw data tables with units, trials, and clear participant labeling (anonymous codes are fine). Then include processed data that helps your reader see patterns: averages, ranges, and variability when appropriate. Graphs should be readable, titled, and labeled so they can stand alone. The key is relevance: include what supports your research question and analysis, not every number you collected. If you’re unsure what “enough” looks like, compare your layout with a few SEHS IA Exemplars and copy the clarity, not the topic.

Can I use secondary literature in an IB SEHS IA?

Yes, and strong IB SEHS IAs usually do. Secondary literature belongs mainly in your background theory and discussion, where you explain mechanisms and interpret results. Use credible, preferably peer-reviewed sources, and reference them consistently. What you should not do is let sources replace your own data: the IA is still an investigation, not a literature review. In the discussion, literature is most powerful when it helps you explain why your results happened, or why they differed from expectations. If you struggle to connect studies to syllabus concepts, use the SEHS IA Guide as your map back to the criteria.

How long does an IB SEHS IA usually take?

Most students underestimate the time because the experiment feels like the “main event,” but writing and refining takes longer. A realistic IB SEHS timeline is 10 to 20 hours total, depending on your complexity and how clean your data is. Planning and piloting often saves time later, because it prevents unusable results. Data collection can be quick, but only if your method is locked and your controls are realistic. The biggest time sink is rewriting the discussion and evaluation once you realize what your data can and cannot claim. Use the IB SEHS IA (2026 syllabus) Grader early to reduce last-minute structural changes.

IB SEHS IA Survival Guide (with RevisionDojo Support)

IB SEHS

• 19 Jul 2026•6

The night before your deadline, your IA stops being “a project” and becomes a mirror. Not of your fitness testing skills, but of your habits: what you measured, what you controlled, what you rushed, and what you avoided because it felt messy.

That’s the quiet truth about IB SEHS coursework. The science is learnable. The stress comes from decisions you didn’t lock in early.

This guide walks you from brainstorm to final submission, with practical checkpoints and RevisionDojo support you can lean on when things get unclear.

IB SEHS IA Checklist (save this)

A focused research question (one IV, one DV, realistic controls)
A method that is safe, repeatable, and measurable
Clean raw data tables (units, trials, averages)
Appropriate processing (graphs + simple statistics when suitable)
Discussion that links results back to IB SEHS theory
Evaluation that shows validity, reliability, limitations, and ethics

A strong home base for all of this is the IB Sports, exercise and health science Resources hub, where notes, Flashcards, and the Questionbank stay connected.

Choose a focused IB SEHS IA topic (safely)

The best IB SEHS IA topics feel small on purpose. One change. One clear outcome. A setting you can actually control.

If you’re still stuck, start with idea prompts that are designed to be testable and syllabus-aligned: Top 10 SEHS IA Ideas That Are Actually Interesting (and Score Well). Then cross-check your theory links using the SEHS IA Guide so your rationale uses IB SEHS language, not just gym talk.

RevisionDojo’s Study Notes and AI Chat help here: you can ask for “mechanisms behind caffeine and reaction time” or “what counts as a confounding variable in a hydration test” and get explanations that keep you inside the syllabus.

Set up valid data collection methods

Most IAs lose marks for reasons that are boring: inconsistent rest time, unclear warm-up, vague participant instructions, or variables that quietly changed.

Make your method replicable. Write it so another student could follow it without asking you a single question.

To tighten your design, practise thinking like an examiner using the IB SEHS IA (2026 syllabus) Grader. In “Draft Mode,” it forces you to check whether your IB SEHS investigation actually demonstrates control, repetition, and measurable outcomes.

Format results and analyse like IB SEHS expects

Your data section should be tidy enough that your future self trusts it.

Use consistent units, label trials, and show averages and variability where appropriate (for example, standard deviation). Then choose graphs that match the story your data can honestly tell.

If analysis feels fuzzy, revise the core skill directly: Measurement and Evaluation of Human Performance and the companion Measurement and Evaluation notes. For quick recall, build daily review with Measurement and Evaluation flashcards.

This is also where RevisionDojo’s Questionbank pays off: it trains you to interpret tables, patterns, and limitations with IB SEHS command-term precision. Start at Questionbank and then drill an SEHS topic area like Skill in Sport Questionbank if your IA leans that way.

Write the IA like a calm person (even if you’re not)

A high-scoring IB SEHS write-up reads like someone made choices on purpose.

Use a clear structure: introduction and research question, method, results, discussion, evaluation, and ethics. Then compare your tone and depth against real standards by studying SEHS IA Exemplars or browsing the wider SEHS Exemplars library.

RevisionDojo’s Grading tools help you avoid “blind spots” (like weak evaluation), and Tutors can give targeted feedback when you need a human to challenge your assumptions.

Final submission: the quiet marks are the easiest marks

Before you upload, do a final sweep for units, labeling, graph readability, and a genuinely critical evaluation. Then run one last check that your wording stays grounded in IB SEHS theory, not just opinion.

If you want the fastest, calmest workflow: use RevisionDojo Study Notes for understanding, Flashcards for retention, the Questionbank for application, AI Chat for quick clarity, the Grading tools for rubric alignment, and the Coursework Library for exemplars. When you treat IB SEHS like a system, your IA stops feeling like a gamble and starts feeling like a plan.
