Analyzing your SEHS IA data effectively is key to scoring high in Criterion B (Exploring) and Criterion C (Analysis). Here’s how to approach it methodically—using RevisionDojo’s resources to guide your methods and interpretation.
1. Understand the Statistical Tools You Need
SEHS Topic 6.1 covers essential statistical techniques:
- Descriptive stats (mean, standard deviation, coefficient of variation)
- Hypothesis testing using paired or unpaired t-tests, correlation coefficients, and r²
- Determining statistical significance (e.g. p ≤ 0.05)
RevisionDojo provides structured flashcards and questions on Topic 6.1 that clarify these methods.

2. Choose the Right Test for Your Study Design
- Use a paired t-test when comparing measurements before/after exercise on the same group
- Use an unpaired t-test when comparing two different groups
- Use correlation analysis if you’re investigating relationships between continuous variables
RevisionDojo’s practice question bank offers real-world examples you can mirror.

3. Report Data Clearly and Transparently
- Present mean ± standard deviation for each test condition
- Include visual representations like scatterplots or bar graphs with error bars
- Label axes clearly and interpret statistical outputs in context
RevisionDojo emphasizes effective visual communication and data clarity for IB scoring.

4. Interpret and Evaluate Your Results
After analysis, discuss:
- Whether your findings met expectations
- Patterns you observed (e.g., dose-response, thresholds)
- Any anomalies or non-significant results—what they mean, and possible reasons
Include potential sources of error (equipment calibration, inconsistent testing conditions) and consider ways to improve your design. RevisionDojo aligns this evaluation approach directly with IA marking criteria.

5. Connect Results to SEHS Theory
Link your statistical findings back to course content:
- Relate changes in heart rate or power output to energy system function or biomechanics
- Explain physiological mechanisms behind significance (or lack thereof)
RevisionDojo’s Ultimate Guide to IB SEHS provides context on theory and data connection across topics.

ℹ️ FAQs
Q: Do I need software for SEHS statistical analysis?
You can analyze data using Excel, Google Sheets, or apps—provided you show all calculations, error values, and reasoning clearly.
Q: What if my results aren’t statistically significant?
That’s fine—as long as you explain possible reasons (sample size, variability) and reflect on study design limitations.
Q: Where can I practice SEHS statistics?
RevisionDojo’s flashcards and question bank cover SEHS Topic 6.1 extensively.
