1. Participant Observation (Overt & Covert)
Overt Participant Observation
Strengths
| Strength | Explanation | Example |

| Researcher becomes biased | “Going native” | Researcher sympathises too much |
| Time-consuming | Requires long involvement | Months in a school |
| Access issues | Some groups deny entry | Gangs, secret groups |
Covert Participant Observation

| Natural behaviour | Participants unaware |
| Higher validity | Real routines observed |

3. Unstructured Interviews
Strengths
