A developmental psychologist is conducting an observational study on cooperative play behaviour in toddlers. The psychologist observed behaviour across six different nurseries (Nursery A to Nursery F).
Table 1 shows the number of pro-social and disruptive behaviours observed during a 20-minute play session for two different age groups: Younger Toddlers (18–24 months) and Older Toddlers (25–36 months).
| Nursery | Younger Toddlers (18–24 months) | Older Toddlers (25–36 months) | ||
|---|---|---|---|---|
| Pro-social | Disruptive | Pro-social | Disruptive | |
| Nursery A | 4 | 9 | 12 | 3 |
| Nursery B | 3 | 12 | 15 | 2 |
| Nursery C | 6 | 8 | 10 | 5 |
| Nursery D | 2 | 15 | 14 | 1 |
| Nursery E | 5 | 7 | 11 | 4 |
