Mean: add all numbers together and divide by the amount of numbers there are. 8 + 9 + 8 + 11 = 36 36/4 = 9 mean = 9
Median: Find the middle number. Since in this case it has an even amount of numbers, add the two middle numbers and divide by 2 8 + 9 = 15 15/2 = 7.5 median = 7.5
Mode: The number that shows up the most Mode = 8
Range: Subtract the smallest number from the largest number 11 - 8 = 3 Range = 3
