Researchers wanted to investigate the relationship between physical activity and emotional well-being in sedentary office workers. They recruited office workers who sit for at least 6 hours a day and asked them to complete two measures over a typical week.
Measure 1: Self-recorded hours of moderate-to-vigorous recreational physical activity during the week (rounded to the nearest hour).
Measure 2: An emotional well-being questionnaire yielding a score from 1 (lowest well-being) to 50 (highest well-being).
The following results were obtained:
Table 1: Physical activity hours and emotional well-being scores of office workers
| Participant | Physical activity (hours/week) | Well-being score (1–50) |
|---|---|---|
| A | 2 | 15 |
| B | 5 | 28 |
| C | 0 | 12 |
| D | 8 | 42 |
| E | 3 | 22 |
| F | 1 | 18 |
| G | 6 | 35 |
| H | 4 | 30 |
| I | 7 | 38 |
