3
To find the mean of a set of data, add all of the numbers in the set (like your teacher does to find your average. Then divide the sum by the number of numbers you added together. ( sum of numbers)/#of numbers = mean

4
I mean, mean, mean To take my average high! ( point to the sky) Repeat While saying these lines, snap fingers

5
To find the median (middle) number in the data, line the numbers up from least to greatest or greatest to least. If there is an odd number of numbers, then it will be the one in the middle If there is an even number of numbers, then take the two in the middle and average them. Example: 80, 82, 85, 90, 97 The 85 is the median.

6
When I stand in the middle, I’m in the median. When I stand in the middle, I’m in the median. When I stand in the middle, I’m in the median. Remember the middle of the highway is called the median.

7
The mode of the data is the number that occurs the most. There can be more than one mode. Or there can be no mode if no numbers recur. Example: 80, 80, 82, 85, 86, 86, 93 80 & 86 are the modes.

8
The mo, mo, most, It is the mode. Repeat

9
To find the range for a set of data, find the difference of the Greatest and the Least. Greatest – Least = Range Data Example: 80, 12, 84, 50, 92 Greatest 92 – Least 12 = 80 (the range)

10
The Greatest less the Least It is the Range Repeat
