The MODE of a data set is simply the number that appears the most often. 

For example, in this set:  [1, 3, 6, 6, 6, 6, 7, 7, 12, 12, 17] - The mode is 6.  This is a UNIMODAL set, and looks like this:

 

In the set: [1, 1, 2, 4, 4] - There are TWO modes (1 and 4), making this set BIMODAL, which looks like this:

 

For sets where there are more than TWO modes, the set is called MULTIMODAL.
