Learning Objectives

  • Explain the importance of controlling for multiple independent variables when predicting a dependent variable.
     
  • Describe the difference between a bivariate correlation and a partial correlation coefficient.
     
  • Interpret a multiple coefficient of determination and be able to calculate the change in the multiple R2.
     
  • Interpret the hypothesis test for a multiple regression model , and understand how it is different from the hypotheses tests for partial slope coefficients.
     
  • Calculate the multiple regression equation and be able to identity it from SPSS output.
     
  • Interpret the partial slope coefficient and its corresponding null hypothesis test.
     
  • Describe how the beta weights are different from unstandardized slope coefficients.
