The degrees of freedom for regression is _________ and for Error is ______
Refer to the ANOVA table for this regression.
Explanation / Answer
The degrees of freedom for regression is _______ and for Error is ____
ANS: 2, 25
F statistic = MS Between / MS within = 598,209/15,174 = 39.423
R2 = SST - SSR / SST = (1,575,756-1,196,417) / 1,575,756= 0.24073
