Question

1.  Imagine that you conducted a correlational study on the relationship between the amount of violence children watch on TV and how aggressively they behave. You measured "amount of violence children watch on TV" by recording the number of hours a group of kids spent watching violent TV shows in a given period of time. You measure aggressive behavior by recording the number of aggressive acts they perform in that same time period.

Would a chi-squared test be the appropriate inferential statistical test to determine if watching violence on TV is related to aggression in the context of this study? Why or why not?

Answer 1

A Chi-squared test would not be the appropriate inferential statistical test to determine if watching violence on TV is related to aggression in the context of this study, because for using a Chi squared test we need a categorical data; while this scenario do not explain about categories of the variables. There are only two variables with no categories. So, in this case we need to use a t-test for the population correlation for checking whether if watching violence on TV is related to aggression in the context of this study.
