Researchers are interested in understanding whether adolescents’ frequency of social media

Question

Researchers are interested in understanding whether adolescents’ frequency of social media use along with the amount of sleep they get at night predict how engaged they are in school. They administered a survey to a group of adolescents and had them report how often they use social media, how many hours of sleep they get at night on average, and how much they like school (all measured on a continuous scale). What statistical test would you use to analyse the data?

 

Options:

Repeated measure ANOVA

Pearson's correlation

Fisher's Exact test

Multiple Linear Regression

Answer 1

Although you are not going to get a proof of cause-and-effect, regression will guide you in predicting one variable's behavior in response to another. In the simplest cases, you will check for a relationship between two variables, but you have three, so it's multiple linear regression.
