A researcher conducted an observational study to investigate whether nursery children (aged 3) and reception children (aged 4) differ in their preference for structured versus unstructured play activities during free time.
The researcher calculated a chi-squared value of χ2=4.21\chi^2 = 4.21χ2=4.21 for the data, with df=1df = 1df=1, using a two-tailed test.
Analyse the results of the chi-squared test to explain what they show about whether nursery or reception children preferred structured or unstructured play activities.
