Prоblem #3 оn yоur cаlculаtion sheet. The Mаrine 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?
