A social psychologist conducted a study on social facilitation, measuring the time (in seconds) taken for 8 participants to complete a complex word-puzzle in the presence of an attentive audience.
The raw data is as follows:
| Participant | A | B | C | D | E | F | G | H |
|---|---|---|---|---|---|---|---|---|
| Time taken (seconds) | 42 | 45 | 47 | 48 | 50 | 51 | 53 | 56 |
Explain which measure of dispersion (the range or the standard deviation) would be more appropriate for this data.
