The coefficient of determination:
A)describes the variation in the dependent variable described by the control variable.
B)tells you the percent of the total variation in the independent variable explained by the dependent variable.
C)ranges from -1.0 to + 1.0.
D)ranges from zero to + 1.0.
E)is a stronger measure than the Pearson correlation coefficient.

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, ranges from zero to +1.0 and represents the proportion of the variation in the dependent variable that is explained by the independent variable(s). Therefore, option D is the correct answer. Option A is incorrect because it isn't describing the coefficient of determination. Option B is incorrect because it seems to be describing the concept of explained variation instead. Option C is incorrect because the coefficient of determination doesn't range from -1.0 to +1.0, as that's the range of the Pearson correlation coefficient. Option E is incorrect because the coefficient of determination isn't necessarily a stronger measure than the Pearson correlation coefficient.
