If the correlation between variables is. 70, what percent of the variance is shared variance?

The correlation between variables = r = 0.70

percent of variance which is shared = ?

to find the shared variance we use the following formula,

r² x 100, here r = 0.70 so,

(0.70) ² x 100 = 0.49 x 100 = 49%

shared variance is 49%

100 - 49 = 51%, which is not shared variance
