| Topic | Non-parametric tests |
| Type | Systematic sampling methods |
| Difficulty | Easy -1.8 This is a straightforward sampling methods question requiring only recall of standard procedures. Students need to describe systematic sampling (select random start, then every kth member where k=240/30=8) and state a textbook advantage (e.g., easier to implement, ensures spread). No calculations, problem-solving, or statistical insight required—purely definitional knowledge. |
