Should see something close to a straight line. Normal Probability Plots – Checks normality of your data.Line Fit Plot charts the predicted results and the actual results by each variable.Residual Plots charts the residuals by each variable.Standardized Residuals is normalized with mean zero and standard deviation of one.Residuals – For every row, it provides the error / difference between predicted and actual values.

Go to the Data tab, right-click and select Customize the Ribbon.If you don’t have the Toolpak (seen in the Data tab under the Analysis section), you may need to add the tool. Y = 1,383.471380 + 10.62219546 * X Doing Simple and Multiple Regression with Excel’s Data Analysis ToolsĮxcel makes it very easy to do linear regression using the Data Analytis Toolpak. 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).
