The following research situation applies to Problem #2 (Pearson correlation) from your calculation sheet. A researcher is interested in whether there is a relationship between self-esteem and depressive disorders. Participants were recruited to answer a series of questions. The first set of questions they answered were designed to measure self-esteem, and the numbers in the X column of your calculation sheet represent the self-esteem scores for each participant (higher values indicate higher self-esteem). The second set of questions that participants answered were part of a checklist about depressive symptoms, with higher scores indicating a greater likelihood of developing (or already meeting the criteria for) a depressive disorder. The scores in the Y column represent the number of items endorsed on the depression checklist. What is the independent variable in this study?

Problem #3 on your calculation sheet. The Marine Life Institute has developed a media campaign designed to decrease the amount of trash pollution in the local harbors. Before the campaign began, researchers measured the amount of pollution (in pounds) pulled from each of the local harbors. After the campaign was over, they returned to the same harbors and measured the amount of pollution (in pounds) left in the harbors. The third data set on your calculation sheet (problem #3) shows how much pollution were present both before and after the media campaign. Column “Pre” shows the amount of pollution before the campaign and Column “Post” shows the amount of pollution after the campaign. We would like to know if the campaign made a difference in the amount of pollution the people caused in the harbors. What is the independent (or quasi-independent) variable in this study?
