Solutions

Expert Solution

1) We are interested in determining if there is a difference in total income based on political affiliation (republican, democrat, independent, other). So, we see that we want to test difference in mean total income for more than two groups. So, the correct answer is:

C. One way ANOVA

2) We want to see whether amount of time someone spends on Twitter is associated with their IQ scores. WE can do this with the help of the correlation coefficient. The correct answer is:

C. Correlation

3) We want to see whether level of Social Media Addiction (continuous scale) differ based on their level of education (no high school, high school graduate, some college, BA/BS, graduate degree). We test difference in mean level of social media addiction for more than two groups. So, the correct answer is:

A. One way ANOVA

4) We want to see whether individual’s stress level is associated with the amount of time they spend in quarantine. The correct answer is:

E. Correlation
