- Plot the residuals on the y-axis against the x-values (independent/explanatory variable) on the x-axis.
Alternatively, you can create a residual plot in Excel by entering the data, creating a scatterplot, displaying the trend line equation, calculating predicted values, and plotting the residuals.
On a TI-84 calculator, you can create a residual plot by entering the data, performing linear regression, and creating the plot.

Suppose we want to fit a regression model to the following dataset: Using statistical software (like Excel, R, Python, SPSS, etc.) we can find that the fitted regression model is: y = 10.4486 + 1.3037(x) We can then use this model to predict the value of y, based on the value of x. For example, if x = 3, then we would … See more
A residual for a given observation in our dataset is calculated as: Residual = observed value – predicted value For example, the residual of the first observation would be calculated as: Residual = 15 – 14.359 = 0.641 We can repeat this process … See more
