Question

Which of the following will increase the statistical power of a hypothesis test?

Obtaining a small effect size

Changing from a two-tailed test to a one-tailed test

Changing α from .05 to .01

Changing the sample size from n = 100 to n = 25

Clear my choice

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
