IB Psychology IA rubric: six criteria (22 marks)
- Introduction (6 marks): Background theory, aim, and hypothesis. IBLens checks whether your introduction clearly links the psychological theory to your experimental design and whether your hypothesis is directional and operationalised.
- Exploration (4 marks): Research design, sampling method, materials, and ethical considerations. IBLens checks whether your design choices are justified and whether you explain how you controlled for confounding variables.
- Analysis (6 marks): Descriptive and inferential statistics, graphs, and interpretation. IBLens checks whether you select the correct statistical test, present results clearly, and interpret the statistics accurately.
- Evaluation (6 marks): Discussion of results in relation to the background theory, limitations, and suggestions for modification. IBLens checks whether your evaluation is specific and whether limitations directly relate to your findings.
Common IB Psychology IA mistakes IBLens catches
- Hypothesis not operationalised: Writing "stress affects memory" instead of specifying what stress manipulation and what memory measure you used.
- Wrong statistical test: Using a t-test for nominal data or a Mann-Whitney U for normally distributed interval data. IBLens checks whether your statistical choice matches your data type and research design.
- Evaluation too general: Listing common Psychology limitations ("small sample size") without relating them to how your specific results may have been affected.
- No ethical considerations: Failing to mention informed consent, the right to withdraw, or debrief procedures in your Exploration section.
