Dr Lin is investigating whether there is a difference in spatial working memory performance when participants are in a high-density sensory environment (using a virtual reality headset) compared to a low-density sensory environment (using a standard screen). She tests 10 participants on a path-recall task where they must remember a sequence of 15 spatial steps.
Table 1 shows the raw data from her experiment.
| Participant number | Number of steps recalled in the 'Virtual Reality' condition | Number of steps recalled in the 'Standard Screen' condition |
|---|---|---|
| 1 | 7 | 11 |
| 2 | 13 | 9 |
| 3 | 5 | 7 |
| 4 | 9 | 14 |
| 5 | 4 | 10 |
| 6 | 11 | 12 |
| 7 | 6 | 8 |
| 8 | 8 | 11 |
| 9 | 5 | 13 |
| 10 | 10 | 6 |
Calculate the range of scores Dr Lin gathered in both conditions of her study.
