Health psychologists investigated the relationship between the number of minutes spent on guided mindfulness meditation per week and self-reported emotional resilience scores in healthcare workers.
The researchers obtained informed consent from 60 participants to track their meditation minutes over a three-week period. After three weeks, the participants' emotional resilience was measured using a standardised scale (ranging from 10 to 50, where higher scores indicate greater emotional resilience).
Table 1 shows the data collected from a sample of 9 of these participants.
| Participant | Emotional resilience score | Guided meditation (minutes/week) |
|---|---|---|
| A | 35 | 45 |
| B | 28 | 30 |
| C | 41 | 60 |
| D | 30 | 35 |
| E | 33 | 40 |
| F | 25 | 20 |
| G | 37 | 50 |
| H | 27 | 25 |
| I | 32 | 42 |
