Feb 249:31 AM
Example:
2, 4, 6, 8, 10
2 + 4 + 6 + 8 + 10 = 30
30/5 = 6
Mean = 6

Median
Mar 31:34 PM
1) Data needs to be in least to greatest order
2) ODD number of values: Middle number will be the median
3) Even number of values: You will need to find the mean of the two middle #'s
Notes
Feb 249:35 AM
Examples:
2, 4, 6, 8, 10
Middle Number is _____
2, 4, 6, 8, 10, 12
