A clinical psychologist investigated the self-talk patterns of clients undergoing Cognitive Behavioral Therapy (CBT). For one week, a group of 8 clients recorded the number of positive and negative self-statements they made each day. The mean scores for each category were calculated.
| Participant | Daily Positive Self-Statements | Daily Negative Self-Statements |
|---|---|---|
| Participant A | 5 | 12 |
| Participant B | 6 | 2 |
| Participant C | 4 | 15 |
| Participant D | 5 | 1 |
| Participant E | 6 | 9 |
| Participant F | 5 | 18 |
| Participant G | 7 | 0 |
| Participant H | 4 | 11 |
| Mean | 5.25 | 8.5 |
State how the standard deviation for positive self-statements would differ from the standard deviation for negative self-statements.
