The coefficient of determination is the percentage of variance in one variable that _________.
A)is accounted for by the variance in the other variable
B)matters only when the other variable is constant
C)equals the square root of the Pearson product-moment correlation coefficient
D)can be determined by taking the square root of the phi coefficient

Question

Quizplus · Accepted Answer

The coefficient of determination measures the proportion or percentage of the variance in the dependent variable that is explained by the independent variable. In other words, it is the amount of variability in one variable that can be accounted for by the variability in another variable. Choice B is incorrect because the coefficient of determination is relevant even when the other variable is not constant. Choice C and D are also incorrect as they describe different types of correlation coefficients that are not directly related to the coefficient of determination.
