The Sample Median

The Problem

The median is the middle number of the sample when the values are ranked from lowest to highest. It is used to estimate the center of a population when the population is highly skewed. To illustrate calculating the median, assume that you collected the following 9 data values:

21, 16, 95, 61, 85, 33, 28, 9, 15

Calculate the median value of this sample, \( \tilde{x} \).
