Question 1 • SC-Statistical Modeling SDPC
In a statistics class, a teacher had the students complete an activity in which they grabbed as many bite-sized pretzels as they could with their dominant hand, without crushing them. The teacher then measured their handspan in centimeters. The scatterplot displays the data the teacher collected along with the least-squares regression line. One student with a handspan of 23 cm grabbed 38 pretzels (this point is circled on the graph)
Answer
A
This point will increase the value of the standard deviation of the residuals because it has a large positive residual.B
This point will increase the value of the standard deviation of the residuals because it has a large negative residual.C
This point will not affect the value of the standard deviation of the residuals because it has a large positive residual.D
This point will decrease the value of the standard deviation of the residuals because it has a large negative residual.
