Input Y Range is where the response variable (Sales in our case) is located. ![]() ![]() If you’re using the CSV or XSLX file, you should mirror these options.

We now have our simple linear regression equation. ![]() The intercept is the “extra” that the model needs to make up for the average case. ![]() To calculate our regression coefficient we divide the covariance of X and Y (SSxy) by the variance in X (SSxx) The sum fields are our SSxx and SSxy (respectively).
