Range­the difference between the largest number and the smallest number in a listexample

Find the range of these numbers: 25, 19, 28, 36, 14highest number ­ lowest number = range

36­14=22Range =22

mean­the number found when the sum of two or more numbers is divided by the number of addends in the sum; also called the average

example

To fine the mean of the numbers 5, 6, 10, first add the numbers.

5 + 6 + 10 = 21

Then, since there were three addends, divide the sum by 3.

21 ÷ 3 = 7

The mean of 5, 6, and 10 is 7.

median ­ the middle number (or the average of the two central numbers) of a list of data when the numbers are arranged in order from the least to greatest

1, 1, 2, 4, 5, 7, 9, 15, 24, 36, 44example

1, 1, 2, 4, 5, 7, 9, 15, 24, 36, 44

mode­the number of numbers that appear most often in a list of data

example

5, 12, 32, 5, 16, 5, 7, 12

­

5, 12, 32, 5, 16, 5, 7, 12

In this set of data, the number 5 appears most often and is the mode
