To create: The group of 10 points in the lower-left corner of the scatterplot with a strong-line pattern with a correlation about 0.9. To construct: The scatterplot and add one point at the upper right that is far from the other 10 points but exactly on the regression line and explain the reason that the upper right point has no effect on the line even though it changes the correlation.

Question

Chapter 5.6, Problem 11AYK

a.

To determine

To create: The group of 10 points in the lower-left corner of the scatterplot with a strong-line pattern with a correlation about 0.9.

To construct: The scatterplot and add one point at the upper right that is far from the other 10 points but exactly on the regression line and explain the reason that the upper right point has no effect on the line even though it changes the correlation.

b.

To determine

To construct: The scatter plot and drag the last point straight down.
