Regression or Correlation for this RQ? Our little group at uni is investigating if there is a relationship between 3 measures of social well-being (social anxiety, social connectedness and self esteem) and usage time (on-screen time in hours) on several social media platforms. Would you recommend that we use correlation or regression in this case?

Thanks in advance :)
You need to provide us with more information on your variables, are they categorical or numerical? If usage time is numerical then you can build a linear regression model and the get the coefficients and associated p-values out of it.

If all variables are numerical you could calculate the correlation between them, but the linear model gives more information / is superior.
