Interpretting

Correlations

Pearsons Values shows the correlation.

Model Summary 

R = Correlation for each model including all predictors in the model 

  • Model 1 = 1 Predictor Variable 
  • Model 2 = 2 Predictor Variables
  • Model 3 = 3 Predictor Variables

R Square = Variance Explained

.334 = 33.4%

R Square Change = The difference from one value to the next - Check Significance!

If insig - run analysis again removing the insig varaible.

ANOVA

Sig values for each model suggests if results are better than chance. 

Coefficients 

Last model - 

B = Correlational Value 

Beta = Larger the Beta the more important the Variable is.

Sig = Significance.
