Textbook Problem

Briefly explain how increasing sample size influences each of the following. Assume that all other factors are held constant.

**a.** The size of the z-score in a hypothesis test

**b.** The size of Cohen’s *d.*

**c.** The power of a hypothesis test

a.

To determine

The effect of increasing the sample si*z*e on a *z*-score in hypothesis test.

Explanation

**Given info:**

The sample si*z*e increases.

**Justification:**

If the *z*-score is increases then that means there is a significant effect and reject the null hypothesis. The *z*-score is calculated as:

Where

b.

To determine

The effect of increasing the sample si*z*e on the si*z*e of Cohen’s *d*.

c.

To determine

Whether the power of a hypothesis test influenced with the increase in sample si*z*e.
