Question

In a test of significance, if all else is held constant, what can be done to increase the power of a test?

Decrease the sample size.

Decrease the significance level.

Decrease the sample size or decrease the significance level.

Increase the sample size or increase the significance level.

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.
