A selection menu. The first heading reads "Types of Residuals" and beneath it, "Raw" is selected and "Standardized" is unselected. The next heading reads "Plot Residuals" and beneath it, "Versus Explanatory Variable" is unselected and "Versus Fitted Values" is selected. Beneath these, is an unchecked box for "Select Variable(s) for Hover Info" and another box is selected in gray for "Histogram/Boxplot of Residuals." A scatterplot of "Audience Score vs. Tomatometer with new observations." The horizontal axis is labeled "Tomatometer" and is labeled in increments of 20, starting at 20 and going up to 100. The vertical axis is labeled "Audience Score" and is also numbered in increments of 20, starting at 40 and going to 80. There are five points on the graph labeled with letters. Point A is at (58, 50), Point B is at (57, 94), Point C is at (22, 72), Point D is at (98, 90), and Point E is at (75, 83). There is a line of best fit that extends from approximately (20, 38) to approximately (100, 84). It travels above point A and below all the other labeled points.People smiling and laughing in a movie theater

extrapolation
using the model to predict for values of the explanatory variable far outside the range in our data.
residual standard error
𝒔𝒆, is a measure of the variability in the residuals.
