In this assignment, you will investigate the relationship between test scores and other variables. First, you will see if the number of hours spent studying for a test affect the test score. Then you will see whether the number of hours slept the night before affect the test score. And finally, you will see if homework scores affect test scores. Once you determine the relationships that may be present, you can compare and interpret the trend lines for those relationships. Based on the description of the scenario, which of the variables is the dependent variable? Along which axis is the dependent variable traditionally plotted?
