1. Choose a Focused IA Topic Safely
Begin with a clear research question: one that fits within the syllabus, allows for practical measurement, and genuinely interests you. Avoid overly broad questions and ensure your approach aligns with the SEHS Core and Options. RevisionDojo provides IA guidance and topic-selection recommendations to keep you on track.

2. Set Up Valid Data Collection Methods
Your investigation should include measurable outcomes, repeated trials, and controlled variables. Seek variety and relevance in your methodology. RevisionDojo’s SEHS topic section includes detailed advice on data collection, analysis tips, and experimental setup. (revisiondojo.com)
3. Format Your Data & Execute Analysis
Record your raw data systematically (tables, units, averages, standard deviations). Use appropriate graphs—such as line, bar, or scatter plots—and apply correlational methods or basic statistical tests where applicable. RevisionDojo offer flashcards and structured notes on Measurement and Evaluation of Human Performance, helping you confidently interpret and evaluate findings. (revisiondojo.com)
4. Structure Your IA Write-Up Clearly
Use the IB Criterion structure:
- Introduction/Research Question
- Methodology
- Results (with graphs and tables)
- Discussion/Evaluation including limitations and ethics
RevisionDojo’s SEHS resources provide exemplar IAs and reliable frameworks matching IB expectations. ()
