Next, we wanted to see if the number of romantic partners in college predicts self-esteem. The same sample of students filled out a self-report measure of self-esteem. The scale used ranged from 1 (very low self-esteem) to 5 (very high self-esteem). Here are the ordered pairs of data we received (first score=number of partners; second score= reported self-esteem).
Partnerships | Self-Esteem |
2 | 2 |
2 | 4 |
4 | 4 |
9 | 4 |
3 | 2 |
0 | 1 |
1 | 3 |
11 | 4 |
6 | 5 |
2 | 1 |
Draw a scatterplot that illustrates the relationship between these two variables.
Calculate r, the correlation coefficient for these two sets of data (round to the nearest hundredth- two decimal places)
