______ measure is equal to the percentage of variance in one variable that is accounted for by the variance in a second variable.
A)Correlation coefficient
B)Pearson's product-moment correlation coefficient
C)Coefficient of determination
D)Coefficient of alienation

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, measures the proportion of variability in one variable that can be explained by the variability in a second variable. It is used to determine how well a regression model fits the data by estimating how much variability in the dependent variable can be explained by the independent variable. Therefore, it is the best choice for the given definition. A is incorrect as it only measures the degree of association between two variables, not the proportion of explained variability. B is the same as the correlation coefficient. D is not a valid statistical measure.
