paired x and y data values have a correlation of -0.6000. What proportion of the variance in the y-values is "accounted for" by the regression line?
---------------------------
r = -0.6
So, r^2 = paired x and y data values have a correlation of -0.6000. What proportion of the variance in the y-values is "accounted for" by the regression line? 0.36 or 36%
------------
36% of the variance in the y-values is accounted for by the regression line.
