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.

Question

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?

Answer 1

In the scenario described, the dependent variable is the test score. This is because the test score is the outcome that you are trying to measure or predict based on the other variables (hours spent studying, hours slept, and homework scores).

The dependent variable is traditionally plotted along the vertical axis (y-axis) of a graph. Meanwhile, the independent variables (such as hours spent studying, hours slept, and homework scores) would be plotted along the horizontal axis (x-axis).
