The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all. The mode in a set of numbers is the number that is most frequently present. To find the mode, it is simply a question of putting the numbers in order and finding the one that appears the most. Where the same value appears more than once, that set of numbers can be two or more modes. Where no value appears more than once, that set will have no mode.
