Paper 3 Question 1: Limits in Interpretation

A detailed IB Psychology Paper 3 Question 1 guide covering nine interpretation limitations and a three-step response structure.

For the 3-mark Question 1, explain one limitation in the source. This guide covers missing sample size, unclear operationalisation, misleading scales, missing spread, category overlap, missing baselines, unclear method, correlation versus causation, and overgeneralised population claims. Each answer should identify the issue, unpack why it matters, and state its impact on interpretation.
