Step 1: place the numbers in order: 1,1,3,4,4,8,9,9,10


Mean = the sum of the numbers divided by the number of numbers (the average) = (1+1+3+4+4+8+9+9+10)/9 = 49/9 = 5.44


Median = the middle number = 4.


Mode is the number that appears most frequently. This set has multiple modes {1,4,9}
Range = the largest - the smallest = 10 -1 = 9.


Midrange = the mean of the largest and smallest = (10+1)/2 = 11/2 =5.5
