Many environmental factors can influence a person's cognitive performance and productivity, including background noise and music. For example, some research suggests that fast-tempo background music increases physiological arousal, which might lead to faster task completion. To investigate this further, psychologists want to use an experimental method to study the effect of music tempo (fast-tempo instrumental music versus slow-tempo instrumental music) on the time taken (in seconds) to complete a standardized data-entry task.
