Mode
Concept
The mode is the value that appears most frequently in a data set. If a data set has multiple values that appear with the same highest frequency, it is considered to have multiple modes. Mathematically, there isn't a formula for the mode in the same way there is for the mean or median; it's more of a count-based operation.
For example, in the data set ([1, 2, 2, 3, 4]), the mode is 2 because it appears more frequently than any other number.
