Mode

　　The mode of a set of numbers is the number that repeats the most in the set.

　　Example:

　　Mode of the set {1,2,3,2,4,5} is 2.

　　The set of numbers {1,2,4,1,2,3,6,8}has two modes:1 and 2.

　　Remember: 

　　There can be more than one number with the highest repeat count. In that case all of them with the highest repeat count are modes.
