Two samples from the same population both have M 84 and s2

Two samples from the same population both have M = 84 and s² = 20.

          One sample has n = 10 and the other has n = 20 scores.

          Both samples are used to test a hypothesis that ? = 80, and to compute Cohen

Solution

The larger sample is more likely to reject the hypothesis but the two samples will have the same value for Cohen’s d.
