So if you wanted to know the percentage of the total variation that is not explained by the line, you could take this number divided by this number. So 2.74 over 22.75. This tells us the percentage of total variation not explained by the line or by the variation in x. By variation in x. And so what is this number going to be? I could just use Excel for this. So if I'm just going to divide this number divided by this number right over there, I get 0.12.
