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.
