The coefficient of determination measures the proportion of ________.
A)explained variation relative to total variation
B)variation due to the relationship among variables
C)error variation relative to total variation
D)variation due to regression

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, measures the proportion of the explained variation in the dependent variable by the independent variable(s) relative to the total variation of the dependent variable. It is calculated as the square of the correlation coefficient (r) and ranges from 0 to 1, with higher values indicating a stronger relationship between the variables. Therefore, option A is the best choice.
