In order to calculate the correlation coefficient, you will need to figure out the data (x and y) from the scatterplot (above). Here is a table to help you out. I’ve already put in all the values for hours spent on social media per day (x) you will just need to find the values for y (self-esteem ratings); Hint: I’ve already done the first two for your: Participant # 1 spent 0 hours on social media, and had a self-esteem rating of 9, Participant # 2 also spent 0 hours on social media, but had a self-esteem rating of 7. You’ll have to do this on a separate piece of paper!
After you’ve filled out the table, let’s check to make sure you’ve got it right. For the person who spent 6 hours on social media, what was their self-esteem rating?
