If SSR = 48 and SSE =12, determine SST, then compute the coefficient of determination r2, and interpret its meaning.
SST = ________
R2 = _________
Interpret the meaning of r2. (Choose correct answer below)
a.) It means that r2 of the variation in the independent variable can be explained by the variation in the dependent variable.
b.) IT means that 1-r2 of the variation in the dependent variable cannot be explained by the variation in the independent variable.
c.) It means that (1-r2). 100% of the variation in the independent variable cannot be explained by the variation in the dependent variable.
d.) It means that r2. 100% of the variation in the dependent variable can be explained by the variation in the independent variable.
