- 1
The mean of a data set is the same as the average, and it is found by adding all the numbers in the set and dividing by the total number of values.
- 2
The median is the middle value in a data set, but to find it, you must first put the data in numerical order.
- 3
The mode is the value that appears most often in a data set; a data set can have more than one mode or no mode at all.
