Step 1: Calculate the sums of x and y Start by renaming the variables to “x” and “y.” It doesn’t matter which variable is called x and which is called y—the formula will give the same answer either way. Next, add up the values of x and y. (In the formula, this step is...

To calculate the total variance (or total variation), you would subtract the average actual value from each of the actual values, square the results, and sum them. This process helps in determining the totalsum of squares, which is an important component in calculating R-squared. From there,...
