WebbBecause X1 and X2 are uncorrelated, we can calculate the shared variance between the two X variables and Y by summing the squared correlations. In our example, the shared variance would be .50 2 +.60 2 = .25+.36 = .61. This turns out to be 61 percent shared variance, and if we calculated a regression equation, we would find that R 2 was .61.
