A researcher is interested in studying how screentime (the amount of time children watch TV or use electronics) influences children's social skills. She compares families who allow their 7 year old children to watch 2 hours of screen time per day to those who do not allow any screentime.

1. What is the independent variable for Scenario B?

The parents

How many books parents read to the children

Whether or not they play violent video games

Reading skills

The amount of screentime (2 hours vs zero hours)

The grade the children are in

The children

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

Two

One

Four

Three

3. What is the dependent variable for Scenario B?

The children's social skills

The amount of screentime (2 hours vs zero hours)

Reading skills

How many books parents read to the children

The children

Whether or not they play violent video games

The parents

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

5. 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.
