Question 83

A psychologist investigates whether posture affects proofreading accuracy. The same 24 adults proofread one passage while standing and immediately afterwards proofread a different passage while seated. The mean number of errors correctly identified in each condition is shown in the table.

ConditionMean number of errors correctly identified

Using the results, explain how completing the seated task second could affect the interpretation of the effect of posture. Suggest one change to the procedure that would reduce the weakness you have explained.
