Dr Aris conducted an observational study to investigate the impact of peer influence on risk-taking behaviour in adolescents. She tested 40 participants using a driving simulator under two conditions: driving alone, and driving while being observed by two friends. At a critical intersection, the researcher recorded whether each participant chose to drive through a changing yellow light or stop.
| Driving Alone | Friends Observing | |
|---|---|---|
| Chose to drive through | 11 | 29 |
| Chose to stop | 29 | 11 |
