Question

What does the variable r2 represent?The sample correlation coefficientThe coefficient of determinationThe population correlation coefficientThe critical value for the correlation coefficient

Answer 1

Given:

Variable r^2

To determine what variable r^2 represents, we first note that it is a statistical indicator of how well the regression predictions match the actual data points in regression. In addition, the coefficient of determination is also denoted as r^2.

Therefore, the answer is:

The coefficient of determination
