Briefly explain how increasing sample size influences each of the following. Assume that all other factors are held constant. The size of the z-score in a hypothesis test. The size of Cohen\'s d. The power of a hypothesis test.

Solution

a)

if Z score increase , then the sample size decrease because is indirectly proportional

b)

if size of Cohens increase, then the sample size increase because we have more accuracy

c)

if the power of test increase , then the sample size increase because the power of test is how much power have the data in the test

if you have a lot of data , then will be powerfull
