An environmental psychologist investigated whether the presence of indoor office plants affects self-reported relaxation. They used a repeated measures design experiment where participants spent 1 hour working in an office workspace under two different conditions.
First, participants completed their tasks in Condition A. A week later, the same participants completed equivalent tasks in Condition B. On each occasion, participants were asked to rate how relaxed they felt on a scale of 1 ('not at all relaxed') to 10 ('extremely relaxed').
The data collected is shown in the table below:
| Participant | Condition A: No plants | Condition B: Many plants |
|---|---|---|
| 1 | 3 | 8 |
| 2 | 5 | 9 |
| 3 | 7 | 6 |
| 4 | 2 | 7 |
| 5 | 4 | 4 |
| 6 | 6 | 8 |
Outline two conclusions that can be made from the data collected in this study.
