Mode
Mode: The value of x that occurs most frequently.
The mode is probably the simplest measure of central tendency. The mode is the value of x that occurs most frequently. However, if two or more values in the sample tie for the highest frequency, there is no mode.
For example, to identify the mode in the dataset {1, 2, 5, 6, 7, 5, 4, 5}, calculate the value that occurs the most. In this dataset the mode is 5.
