Lecture 7: Multiple Regression

Question 1

Difference between bivariate and multiple regression

Answer 1

Bivariate accounts for variance in criterion using one predictor, multiple uses more than one predictor

Question 2

Validities

Answer 2

Show whether our predictors are valid predictors for our criterion

Question 3

Tolerance (TOL) < .2 indicates what

Answer 3

multicollinearity, which we do not want , therefore we want TOL greater than .2

Question 4

Variable inflation factor (VIF) > 5 indicates what

Answer 4

multicollinearity, which we do not want, therefore we want VIF less than 5

Question 5

What SPSS table is looked at for predictive utility in multiple regression

Answer 5

ANOVA

Question 6

sr^2 ( squared semi partial correlation) tell us

Answer 6

Proportion of unique variance accounted for

Question 7

sr

Answer 7

Part correlation
