Textbook Problem

A sample of *n* = 25 scores has a mean of *M* = 83 and a standard deviation of *s* = 15.

a. Explain what is measured by the sample standard deviation.

b. Compute the estimated standard error for the sample mean and explain what is measured by the standard error.

**a.**

To determine

**To Find:** What is measured by sample standard deviation.

Explanation

Standard deviation measures the spread of the data. It measures the distance between each data point and the mean...

**b.**

To determine

**To find:** Estimated standard error for the sample means in the given question and explain what it measures.
