![]() ![]() The independent variables are IQ and study hours, In this equation, ŷ is the predicted test score. Since we have two independent variables, the equation takes the following form: The first task in our analysis is to define a linear, least-squares regression equation to predict test score,īased on IQ and study hours. Let's review the output produced by Excel and see how it addresses each task. Assess the contribution of each independent variable (i.e., IQ and study hours) to the prediction. ![]()
