what is the mean math definition
But there is no middle number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values: (2 + 4) Ã· 2 = 6 Ã· 2 = 3. The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode.
