Elena wanted to investigate whether toddlers (aged 2 to 3 years) exhibit more sharing behaviour when playing with a single large collaborative play table or multiple individual play trays. She set up a playroom at a local nursery with either one large collaborative play table or four individual play trays. Elena sat behind a one-way mirror to observe and record the number of toddlers demonstrating high or low sharing behaviour during their free-play sessions.
Elena's results are shown in Table 1.
| Play setup | High sharing behaviour | Low sharing behaviour |
|---|---|---|
| Single large collaborative table | 14 | 5 |
| Multiple individual play trays | 4 | 13 |
Explain one strength and one weakness of Elena using an observation for her investigation.
