A researcher records hippocampal volume and self-esteem scores for six participants.
| Participant | Hippocampal volume (cm³) | Self-esteem score (out of 40) |
|---|---|---|
| A | 6.2 | 18 |
| B | 6.8 | 21 |
| C | 7.1 | 24 |
| D | 7.6 | 27 |
| E | 8.2 | 31 |
| F | 8.9 | 35 |
Describe the relationship shown by the data and explain two reasons why the data cannot show that a larger hippocampal volume causes higher self-esteem.
