LibGuides: Mathematics: Mean, median and mode

MEAN, MEDIAN AND MODE

In this module, you can study the basic statistical measures: mean, median and mode.

When most people say "average" they are talking about the mean of a data set.

However, the mean, median and mode are actually all "averages."

Some data sets have no mode, and some have more than one mode!
