The list represents a sample, as it is a subset of the larger population (all psychology majors in the United States) that the chair is interested in studying. An experimental group would involve manipulating a variable and comparing it to a control group. A population refers to the entire group being studied, while a case study involves in-depth analysis of a single individual or specific group.
