Finally, let's meet the last measure of central tendency, the mode. The mode is the value that occurs most frequently in a dataset. It can be used with numerical and non-numerical data. Consider this set:

0, \mathbf{1}, \mathbf{1}, \mathbf{1}, \mathbf{1}, 2, 2, 2, 3, 3, 3, 4, 5

The most frequent value in this set is 1. Now let's take a look at this set:

0,\mathbf{1},\mathbf{1}, \mathbf{1}, \mathbf{2}, \mathbf{2}, \mathbf{2}, \mathbf{3}, \mathbf{3}, \mathbf{3}, 4, 5

There is no unique most frequent value in this set: the numbers 1, 2 and 3 each occur three times. Therefore, there is no mode for this set.
