Mode is the value which occurs most frequently in the given set of data. If the distribution has one mode, it is called Uni-modal distribution, while distribution with two modes is called Bi-modal distribution. Distribution which has more than two modes is called Multi-Modal distribution.
Example
Find mode of the following data:
10, 11, 13, 1, 15, 11, 7, 9, 12, 14, 17
Solution
Our first step here is to arrange the data:
1, 7, 9, 10, 11, 11, 12, 13, 14, 15, 17
You can see that 11 is the most repeated value, therefore, it is the mode of the distribution.
Mode = 11
