- Making a Residual Plot \\ A residual plot helps us assess the line of best fit or trend line we have drawn—how good, or accurate is it? It is a plot of residual values. Let's st…

- Residual plots Before diving into analyzing residual plots, let's review. Whenever we plot either a line of best fit or a trend line for a scatter plot, we find that not every p…
