The following is a residual plot of a linear regression. A line would not be a good fit for these data. Why not? Is the regression equation likely to underestimate or overestimate the y-value of the point in the graph marked with the square?

The residual is negative because the data point fell below the line. A residual plot is a scatterplot of the regression residuals against the explanatory variable (or equivalently, against the predicted y-values). Residual plots help us assess how well a regression line fits the data. Assignment: p. 220-221—3.39, 3.40, 3.42. How Well the Line ...

Find and interpret the residual for this month. In Homework 3.1, you were presented with data on the lean body mass and resting metabolic rate for 12 women who were subjects in a study of dieting. Lean body mass, given in kilograms, is a person’s weight leaving out all fat.

The least-squares regression line always passes through the point ... What is a residual plot? Sketch a graph of a residual plot. If a least-squares regression line fits the data well, what two characteristics should the residual plot exhibit? What is the standard deviation of the residuals? How is it interpreted?

Points in the residual plot that lie below the horizontal axis, lie below the LSRL. Therefore the model gives an overestimate at that point. Therefore negative residuals represent overestimates. The LSRL is not a good model if the residual plot shows a pattern. Construct a well-labeled residual plot using the data on jet ski fatalities from #1.

(a) This student has a grade point average of 2.9 and an SAT Math score of 670. (b) If we used the least-squares line to predict this student’s SAT Math score, we would make a prediction that is too low. (c) This student’s residual is –82.23. (d) Removing this data point would cause the correlation coefficient to …
