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.
