Question
If SSR=23 and SST = 92, compute the coefficient of determination, r, and interpret its meaning. r = L(Type an integer or a decimal) What is the meaning of 122 0 A. ? of the variation in the independent variable can be explained by the vanation in the dependent van O B. . 100% of the variation in the dependent variable can be explained by the vanation in the independe O e. (1- .100% of the variation in the independent variable cannot be explained by the variation in the d O D 1-r2 o the variation in the dependent variable cannot be explained by the variation in the independent va Click to select your answer(s)Explanation / Answer
Given:-
SSR = 23 and SST = 92 ,Now to find a coefficient of determination r2
r2 = SSR / SST = (23 / 92) = 0.25
Meaning of r2 :- Option "B" is correct.
r2 * 100 of the variation in the dependent variable can be explained by the variation in the independent varibale.
( i.e r2 is the proportion of the variance in the dependent variable that is predictable from the independent variable. )
