Basic Methods of Describing Data

Measures of Central Tendency (mean, median, mode) 

A measure of central tendency is information that conveys something about the "middle-ness" of some data. It is information that takes in the "big picture" of how the data is organized and compresses that into one measurement that captures something about the essence of the "ordinary middle" of the data. The three measures of central tendency are mean, median, and mode. Each one tells a slightly different story about the middle because each is figured out differently.
