Question: A social psychologist records the number of outbursts among students at two schools. Assuming the same number of students were observed at each school, what is the
Results: sample size = 20 for each school
For a two tailed test and df = 38, at 0.05 significance level, t = 2.023 (from t distribution table)
Here, the critical value is less than t obtained (t2.023 < 4.19)
Hence, we reject the null hypothesis at a 5% significance level
Given that d = 0.25 => effect size is medium (since 0.2<d<0.8 for medium)
Therefore, the study showed a medium effect size
