MEAN!
-arrange data in ascending order
-the sum of all data










MEDIAN!
-great to use if there is an outlier
-Find middle number
-data must be arranged in numerical order
-if there are 2 middle numbers,you find the mean of them


















MODE!
-Find the most common number in the set of data
-arrange data in ascending order
-you can have more then one mode or you can have no mode









RANGE!
-arrange the data in ascending order
-subtract the smallest data from the largest data
-Large Range=Outlier
