English Grammar Rule - Medium and Median

Today's English Grammar Rule defines the often misused terms median and medium:

Median in the barrier (usually grassy or concrete) between lanes of traffic on a roadway; the midpoint in a series of numbers--but not necessarily the average, a term used in statistics that indicates the midpoint of distribution.

Medium has several definitions: average quantity or quality, someone who serves as an liaison between the living and the dead, a means for storing or communicating information (plural is media), and there are several other widely accepted definitions for this word.
