Two samples from the same population

Reference no: EM13496597

Two samples from the same population both have M = 84 and s2 = 20, however one sample has n = 10 and the other has n = 20 scores. Both samples are used to evaluate a hypothesis that ? = 80 and to compute Cohen’s d. How will the outcomes for the two samples compare?

1. The larger sample is more likely to reject the hypothesis and will produce a larger value for Cohen’s d.

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

3. The larger sample is less likely to reject the hypothesis and will produce a larger value for Cohen’s d.

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