Go back to Q1 Noob.
Nope, you must have been putting signs on people’s backs instead of paying attention.

Go back to Q1
NO, Nyshad must’ve answered this one…

Go to Q2
OH YEAH! The scatter plot of the regression residuals
against the explanatory variable is a Residual Plot.

Go back to Q2.
No way jose.

Go back to Q2 Miguel
No

Go to Q3
BYAHHH!Positive Association is present in this graph. The
definition of positive association is when above-average values of one tend to accompany above-average values of
the other and below –average values also tend to occur together.

Go back to Q3
Wrong!
![Page 12: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/12.jpg)
Go to Q4
Correct! The explanatory variable attempts to explain the observed outcome.

Go back to Q4
That is a sine curve sigh…

Go back to Q4 lefty
No Tran maybe next time you shouldn’t be sleeping.
![Page 16: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/16.jpg)
Go to Q5
You are correct! This is a scatter plot. A scatter plot shows the relationship between two quantitative
variables measured on the same individuals.
![Page 17: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/17.jpg)
Q5: What are individual points that substantially change the regression line?
Correlation Coefficient MeanInfluential Observation
![Page 18: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/18.jpg)
Go to Q6
Correct you are, Influential Observations are points that can substantially change the
regression line.

Back to Q5
You are NOT Correct
![Page 21: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/21.jpg)
Q6: What is it called when above-average values of one variable tend to accompany
below-average values of the other, and vice versa.
Negative Associated Variables Lurking variablesUneven Variables
![Page 22: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/22.jpg)
Go to Q7
You got lucky this time, the negative association is when above-average values
of one variable tend to accompany below-average values of the other, and vice
versa.
![Page 23: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/23.jpg)
Go to jail, do not pass go, do not collect 200
dollars, go back to question 6
Do you even pay attention in class?
![Page 24: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/24.jpg)
Goin back
Maybe you should actually try reading the chapter like Mrs. Nienhaus tells you to.
![Page 25: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/25.jpg)
Q7: The formula for residual is:
Ŷ-y y-ŷNot that useful

Go to back to Q9
Try again. I know you can do it
![Page 33: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/33.jpg)
Go to Q10
Good Job! You are right! A quantity that gives the quality of a least squares fitting to the original data is the Correlation Coefficient.
![Page 34: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/34.jpg)
Q10: Which of the following determines how close the points in the scatter plot lie to a
simple form such as a line.
Form SpreadStrength
![Page 35: AP Stats Chapter 3 Review. Question 1: What is a scatter plot of the regression residuals against the explanatory variable? Residual PlotStem and Leaf.](https://reader035.fdocuments.in/reader035/viewer/2022070416/5697c0151a28abf838ccdf05/html5/thumbnails/35.jpg)
End!
YES! The strength of a relationship is determined by how close the points in the
scatter plot lie to a simple form such as a line.
