# 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:

53, 29, 18, 42, 98, 42, 63, 96, 2

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