The mode of a data set refers to the number that occurs most often. If there is not a number that occurs more than any other, we say there is no mode for the data. It is possible to have more than one mode for a data set.

If you put this data set in numerical order you have:

0, 0, 0, 0, 1, 1, 2, 2, 2, 2, 3, 4, 4, 4, 4

This data set has 3 modes because 0, 2, & 4 all appear 4 times which is the max in the data.
