Question

If SSR = 21 and SST - 84, compute the coefficient of determination, r^2, and interpret its meaning. What is the meaning of r^2? 100% of the variation in the independent variable cannot be explained by the variation in the dependent variable. 1 - r^2 of the variation in the dependent variable cannot be explained by the variation in the independent variable. R^2 of the variation in the independent variable can be explained by the variation in the dependent variable. R^2 100% of the variation in the dependent variable can be explained by the variation in the independent variable.

Explanation / Answer

a.

r^2 = SSR/ SST = 21/84 = 0.25

b.

r^2 of the variation in the independent variable can be explained by the variation in the
dependent variable.
