A social psychologist investigated impetuous decision-making using an impulse-control questionnaire (where higher scores indicate poorer impulse control). The sample consisted of ten participants diagnosed with Gaming Disorder (Group A) and a matched control group of ten healthy participants (Group B). The raw data is presented in Table 1 below.
| Participant | Group A (Gaming Disorder): Impulse-control score | Participant | Group B (Control Group): Impulse-control score |
|---|---|---|---|
| 1 | 42 | 1 | 14 |
| 2 | 15 | 2 | 28 |
| 3 | 22 | 3 | 32 |
| 4 | 58 | 4 | 29 |
| 5 | 20 | 5 | 65 |
| 6 | 24 | 6 | 30 |
| 7 | 61 | 7 | 36 |
| 8 | 20 | 8 | 25 |
| 9 | 26 | 9 | 20 |
| 10 | 23 | 10 | 27 |
Complete Table 1 by calculating the median and range for both groups. Then, explain why the researcher chose to use the median rather than the mode as a measure of central tendency for this dataset.
