Simple linear regression SAS Codes
A researcher hypothesizes that undergraduate students who are satisfied with their lives will sleep less than those who are not satisfied. To test this hypothesis, she selects a sample of undergraduate students and asks them to maintain a “sleep log” (Drowsy, 1977), keeping track of the number of hours they sleep during each 24-hour period. These logs are maintained for two weeks. At the end of the two-week period, each participant completes the Satisfaction with Life Scale (Giggle & Smirk, 1969), a reliable, validated measure of general satisfaction with life.
These are the data the researcher obtained:
Participant | Mean Hours of Sleep | SWL Score |
01 | 7.5 | 23 |
02 | 8.3 | 19 |
03 | 9.5 | 16 |
04 | 8.5 | 20 |
05 | 6.0 | 40 |
06 | 8.0 | 22 |
07 | 7.3 | 30 |
08 | 7.0 | 25 |
09 | 8.0 | 30 |
10 | 6.5 | 36 |
