A cognitive psychologist conducts an experiment to compare reaction times (in milliseconds) under two conditions: Condition A (with background music) and Condition B (in silence). The psychologist calculates the standard deviation for both conditions to measure dispersion. Under Condition A, the reaction times are highly varied and spread out, while under Condition B, the reaction times are highly consistent and clustered close to the mean.
State how the standard deviation for Condition A would differ from the standard deviation for Condition B.
Practise AQA A Level Psychology Research methods with exam-style questions for A Level Psychology. 100 questions covering Experimental method, Observational techniques, Self-report techniques, Correlations, Content analysis (A-level only), Case studies (A-level only), Scientific processes, Data handling and analysis, and Inferential testing (A-level only), matched to the AQA A Level Psychology (7182) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
