Mean, Median, Mode, and Range
The mean of a group of numbers is the average of the numbers.
eg., 3, 5, 6, 8, 13.
Add all the numbers together (3+5+6+8+13=35) then divide the total (35) by the number of numbers added together (5), so 35 ÷ 5 = 7. The mean is 7.
The median of a group of numbers is the number that is exactly in the middle when the numbers are arranged numerically.
eg., 3, 5, 6, 8, 12. The physical middle number is 6.
(If the set contains an even number of numbers, the median is the still the middle,
eg., 6 & 7. The median is 6.5)
The mode of a group of numbers is the number that appears most often.
eg., 3, 5, 5, 6, 8, 12. The number that is the most common is 5. The mode is 5.
(If there are several numbers that are tied for being the mode, then they are all the mode.)
The range of a group of numbers is the difference between the biggest number and the smallest number.
eg., 3, 5, 6, 8, 12. The range is 12 - 3 = 9.
