Dr. Genevieve conducted a study to investigate how a defendant's accent affects mock jurors' decisions regarding guilt. She posted an advertisement on a local town community Facebook group, asking for adult volunteers to participate in an online study.
Those who responded were randomly allocated to one of two groups and listened to an audio recording of a mock trial:
Dr. Genevieve then asked all participants to rate how likely it was that the defendant committed the crime. 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 Dr. Genevieve and explain one limitation of using this technique in this study.
Identify the independent variable (IV) and the dependent variable (DV) in this study.
