Means and Medians

The mean and median are familiar tools to help summarize central tendencies in quantitative data.

To calculate the mean one adds up the observed values and divides by the number of observations.

The median is the data point in the “middle” of the data. As many observations are greater than the median as are less than the median.

In a legal context, it is often of interest to know whether the means or medians of two groups of cases differ to a significant degree.
