What a good answer should say
- A strong answer gives AO1 knowledge about Spearman's rho, applies it to the question context, and adds AO3 evaluation by explaining whether research evidence, validity, reliability or bias supports the claim.
- For statistics objectives, name the statistic, test, probability, significance level or decision rule so the conclusion follows from the data.
Explanation
Why this works
This question checks whether the learner can turn the approved Psychology objective into AO1 knowledge and AO3 evaluation rather than listing a topic label.
