Presentation transcript:

Simple Linear Regression Open the ‘Management Trainee Test Scores’ file Under the Data tab, click on Data Analysis Choose Regression then OK

Simple Linear Regression The Dependent Variable (y) is Test Score, so for Input Y Range: choose B1:B10 The Independent Variable (x) is GPA, so for Input X Range: choose A1:A10 When defining our variables, the labels were in the first row of the Input Range, so check Labels Click OK
