Dr. Julian conducts an experiment to test the hypothesis that when more witnesses to a crime are present, any one witness is less likely to help the victim.
After providing a cover story, she randomly assigns participants to witness a staged crime either alone, in the presence of two other people, or in the presence of ten other people. Then, she assesses how many people make an effort to help. Identify the independent and dependent variables in this study.
What will be an ideal response?
