   Question

   A researcher performs a regression analysis using SPSS and receives the following ANOVA table:

   

   How much variance of Y is explained by this regression model?

   
   
   1. FALSE: 4.2%
   2. FALSE: 4.8%
   3. TRUE: 5.1%
   4. FALSE: This can not be calculated on the basis of the above output.
   
   

   Solution

   You can calculate the R² by (total sum of squares -residual) / total sum of squares=(2564,601-2433,288)/ 2564,601= 131,313/2564,601=0,051
   Thus 5,1 %
