The coefficient of determination has a value between ______.
A)0 and 1
B)-1 and +1
C)-∞ to +∞
D)-1 to 0

Question

Quizplus · Accepted Answer

The coefficient of determination (R-squared) is a measure of how well a regression model fits the data, and its value ranges from 0 to 1, where 0 indicates no correlation between the predictor and response variables, and 1 indicates a perfect fit. Therefore, the best choice is A. The other options (-1 to +1 and -∞ to +∞) refer to different measures of correlation, but not specifically to the R-squared value. Similarly, the range of -1 to 0 is not valid for R-squared, as it implies a negative correlation between the variables.
