Use your responses to Step A to reduce the list of Table B variables for this question. So, if you removed Midterm Exam Grade in Step A, it should not be included in Step B. In order to select a subset of predictor variables that provide the most useful understanding of the factors influencing the dependent variable, we must consider the increase in cumulative variance explained (R) when we add the variable. In this case, assume that you set a minimum increase of 3% in explained variance for a variable to be included. What variables would remain in the mix if we applied this rule
