find the mean, range, and median of these values 12,4,-2,0,9.-2,1,7,8,2 recall the range is calculated by finding the difference between the largest and smallest data values. hurry

Put numbers in order

-2,-2,0,1,2,4,7,8,9,12

Mean add all the numbers = 39 divide 39 by the number of of numbers on the list which is 10. 39/10 = 3.9

Mean = 3.9

Range is the number of spots between - 2 and 12 = 14

Range = 14

Median is the middle number in the list there are two middle numbers 2 and 4. Add these together to get 6. Divide 6 by the number 2 because that is how many numbers you had to add. 6/2=3. The is not on the list but it is the average of the two terms.

Median = 3
