Explain how experimental helps psychologists address this objective: Explain how experimental design affects the choice of statistical test..
Model answer
What a good answer should say
- A strong answer gives AO1 knowledge about experimental, applies it to the question context, and adds AO3 evaluation by explaining whether research evidence, validity, reliability or bias supports the claim.
- Where the objective uses statistical language, identify the statistic or statistical infrequency concept explicitly.
- For research-method objectives, identify the method, variables, controls, conditions, validity, reliability or sampling issue before drawing the conclusion; sampling points should link the sample to population, bias, representativeness or generalisation.
- 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.
