A social psychologist investigated conformity to social roles using a simulated prison environment. They recorded the number of aggressive verbal statements made by 9 "guards" during a standard 2-hour observation period.
The raw data for the 9 participants is as follows:
| Guard | A | B | C | D | E | F | G | H | I |
|---|---|---|---|---|---|---|---|---|---|
| Number of aggressive statements | 12 | 14 | 15 | 15 | 16 | 16 | 17 | 18 | 21 |
Explain which measure of dispersion (the range or the standard deviation) would be more appropriate for this data.
