Scenario A. The manager at Dunder-Mifflin Paper Company interested in understanding how a company's employee benefits influence employee satisfaction. In 2020 the company implemented a new benefits package that included optional benefits such as childcare, eldercare, and retirement packages. The manager compares the employee satisfaction ratings from before and after the new benefits package was implemented.

4. What is the confound for Scenario A (You may list more than one, but you must give at least one!).

5. How could the confound be fixed for Scenario A? Be sure to tell me what technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well as how you would apply that technique to this specific scenario, and how that would fix this confound.

Scenario B.A researcher is interested in studying whether a new app can help improve first graders' reading skills. She recruits two first grade classes from a local elementary school: classroom 1 uses the app for 30 minutes each day and classroom 2 does not use the app. She compares their reading ability at the end of the school year.

6. What is the independent variable for Scenario B?

a. Reading skills

b. The amount of screentime (2 hours vs zero hours)

c. The grade the children are in

d. The children

e. The app (whether or not the children use the app)

f. The parents

g. How many books parents read to the children

7. How many levels are there for the independent variable in Scenario B?

a. Four

b. Three

c. Two

d. One

8. What is the dependent variable for Scenario B?

A. Social skills

B. The parents

C. The amount of screentime (2 hours vs zero hours)

D. How many books parents read to the children

E. Reading skills

F. The app (whether or not the children use the app)

G. The children

9. What is the confound for Scenario B (you may list more than one, but you must give at least one!).

10. How could the confound be fixed for Scenario B?Be sure to tell mewhat technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well ashow you would apply that technique to this specific scenario, andhow that would fix this confound.

Scenario C. A new vitamin supplement was advertised to increase concentration and memory ability. The company decides to test this claim so that they can strengthen their advertisements. They recruit a sample of customers and compare the memory ability of participants that have reported taking the new supplement to those who have reported that they do not take the supplement and finds that those who reported taking the supplement had better memory than those who did not.

15. How could the confound be fixed in Scenario C? Be sure to tell mewhat technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well ashow you would apply that technique to this specific scenario, andhow that would fix this confound.

Scenario D.A researcher is interested in examining how loud music can influence driving ability. They randomly assign participants to either listen to loud music of their choice, soft music of their choice, or no music and then measures the number of driving mistakes they make on a closed driving course.

16. What is the independent variable for Scenario D?

A. Music volume

B. The participants

C. The car

D. The quality of the speakers in the car

E. Number of driving mistakes

D. Music volume

E. The participants

19. What is the confound for Scenario D (you may list more than one, but you must give at least one!).

20. How could the confound be fixed in Scenario D? Be sure to tell mewhat technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well ashow you would apply that technique to this specific scenario, andhow that would fix this confound.
