Question

Quizplus · Accepted Answer

The coefficient of determination (also known as R-squared) is always non-negative and ranges from 0 to 1. It represents the proportion of the variance in the dependent variable (Y) that is accounted for by the independent variable(s) (X). Therefore, it cannot be negative and option B is not true. Options A, C, and D are all true.
