How Can I Use Excel to Test for the Significance of the Correlation Coefficient?
We are using the following example to examine whether the correlation between number of hours spent using social media per week is significantly related to level of self-rated job satisfaction on a scale from 1 to 10, with 10 being highest.
The research hypothesis is that the two variables are positively related, and we will use a one-tailed test at the.01 level of significance. Each participating adult in this study recorded the number of hours per week he or she spent on such activities as Twitter, Facebook, etc., as well as their self-rating of job satisfaction.
Here are the data:
Social Media Hours | Job Success |
22 | 5 |
23 | 6 |
15 | 5 |
7 | 3 |
21 | 9 |
14 | 5 |
15 | 6 |
22 | 7 |
20 | 8 |
19 | 9 |
