Dr. Brenda carried out an experiment to investigate the effect of a defendant's regional accent on mock jurors' perception of guilt. She selected her participants from individuals available in a university cafeteria during lunchtime on a Tuesday.
She played a five-minute audio recording of a police interview to two separate groups of participants:
Brenda then asked all participants to rate the likelihood that the defendant was guilty. This was measured on a scale of 1 to 7, where 1 represented 'definitely innocent' and 7 represented 'definitely guilty'.
Identify the sampling technique used by Brenda and explain one limitation of using this technique in this study.
Identify the independent variable (IV) and the dependent variable (DV) in this study.
