Median: The middle number in a set of data. Example A: 1,3,5,7,9- Median is 5 Hint: Always rewrite the numbers from least to greatest to make it easier to find the median. Example B: 2,4,6,8- There are two middle numbers (4 and 6) so you find what number is right between them (answer-5) Set 1: 12, 12, 7, 9, 10 Rewrite: 7, 9, 10, 12, 12 Median: 10 Set 2: 4,2,4,4,2,2 Rewrite: 2, 2, 2, 4, 4, 4 Median: 3 Set 3: 54, 53, 56, 54, 55 Rewrite: 53, 54, 54, 55, 56 Median: 54

Set 1: 12, 12, 7, 9, 10

Rewrite: 7, 9, 10, 12, 12

Median: 10

Set 2: 4,2,4,4,2,2

Rewrite: 2, 2, 2, 4, 4, 4

Median: 3

Set 3: 54, 53, 56, 54, 55

Rewrite: 53, 54, 54, 55, 56

Median: 54

Mean: The average, add all of the numbers in a set and divide by how many numbers are in the set. Example: 3,4,1,4,3 3 + 4 + 1+ 4 + 3=15 There are 5 numbers 15÷5= 3

Example: 3,4,1,4,3

3 + 4 + 1+ 4 + 3=15

There are 5 numbers

15÷5= 3
