   Question

   A multiple regression analysis gives the following results:

   Model	Sum of Squares	df	Mean Square	F	Sig.
   Regression	81.580	2	40.790	91.932	.000
   Residual	393.115	886	.444
   Total	474.695	888

   How much of the variance of Y is explained by the independent variables?

   
   
   1. FALSE: 91.932%
   2. FALSE: 0.000%
   3. TRUE: 17.2%
   4. FALSE: 20.8%
   
   

   Solution

   You can calculate the R² by (total sum of squares - residual) / total sum of squares = 0.172

   If you want to know more about the explained variance, the R² watch this clip.

   
   
   1. False
   2. False
   3. True
   4. False
