WebbThe simple answer is that R2is usually a fraction between 0.0 and 1.0, and has no units. But there are special cases: •R2equals 1.00 when the curve goes through every point. But if you have replicate Y values at the same X value, it is impossible for the curve to go through every point, so R2has to be less than 1.00.

WebbSo if you want the amount that is explained by the variance in x, you just subtract that from 1. So let me write it right over here. So we have our r squared, which is the percent of the total variation that is explained by x, is going to be 1 the minus that 0.12 that we just calculated. Which is going to be 0.88.
