The Sample Mean

The Problem

The mean is what we usually term the “average,” although there are many different averages, including the median. The mean is also known as the center of gravity of the data. It is used to estimate the center of a population when the population is not highly skewed. To illustrate calculating the mean, assume that you collected the following 6 data values:

96, 18, 19, 81, 95, 2

Calculate the mean value of this sample, \( \bar{x} \).
