A social psychologist conducted a study on minority influence, measuring the number of trials (out of 20) it took for participants to publicly agree with a minority accomplice. The raw data for the 8 participants is as follows:
| Participant | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Number of trials | 4 | 5 | 5 | 6 | 6 | 7 | 7 | 8 |
Explain which measure of dispersion (the range or the standard deviation) would be more appropriate for this data.
