IV – DV Exercise

For the experiment described below, specify the following: the independent variable, the dependent variable, the sample, and the population.

A psychology professor, interested in gender differences and similarities, conducts an experiment to determine if women remember emotional events better then men. Fifteen female and 15 male undergraduate students are randomly sampled from the students enrolled in a very large section of Psychology 101; the females are assigned to Group 1, and the males are assigned to Group 2. Each student is shown a set of 20 highly emotional pictures, and allowed to study each for one minute. Two weeks later they are tested for recall of the details of each picture. The percent of picture details recalled by each student is determined, and averages for each group are compared to determine if gender affects recall of emotional events.

The percent of picture details recalled by each student is determined, and averages for each group are compared to determine if gender affects recall of emotional events.

Independent Variable: Gender (w/ 2 levels: Male and Female)

Dependent Variable: Memory for Emotional Events

Sample: 15 males and 15 females (randomly selected students)

Population: Students enrolled in very large section of Psychology 101
