Question 6.109

6.109 Explain power and sample size.

Two studies are identical in all respects except for the sample sizes. Consider the power versus a particular sample size. Will the study with the larger sample size have more power or less power than the one with the smaller sample size? Explain your answer in terms that could be understood by someone with very little knowledge of statistics.

The one with the larger sample size will have more power. More data will provide more information, which should give us a better chance of finding differences between the data and the hypothesis.
