An occupational psychologist conducted a study to investigate whether different types of afternoon break activities affect employee focus levels. She compared software engineers who participated in a 10-minute active physical stretching session immediately before a coding task with those who spent 10 minutes in a quiet coffee area.
She obtained a random sample of engineers from a technology firm. A structured self-assessment questionnaire was used where each engineer's post-break focus level was rated on a scale from 1 to 10, with 10 indicating extremely high, sharp focus.
A table to show the frequency of post-break focus ratings, median ratings, and ranges for software engineers in the active stretching group and the quiet coffee break group.
| Focus Rating | Frequency from Active Stretching Group | Frequency from Quiet Coffee Break Group |
|---|---|---|
| 1 | 0 | 1 |
| 2 | 1 | 2 |
| 3 | 2 | 6 |
| 4 | 3 | 9 |
| 5 | 5 | 6 |
| 6 | 7 | 4 |
| 7 | 8 | 2 |
| 8 | 4 | 0 |
| 9 | 1 | 0 |
| 10 | 1 | 0 |
| Median Rating | 6 | 4 |
| Range | 8 | 6 |
Outline a conclusion that can be drawn from the above table. Refer to the median ratings as part of your answer.
