Answer:
mean = 19.54
median = 17
mode 16
range 52
Step-by-step explanation:
17, 22, 34, 3, 16, 16, 24, 55, 18, 3, 16, 12, and 18
First put the numbers in order from smallest to largest
3, 3, 12, 16, 16, 16,17,18, 18,22,24, 34, 55
The mean is where you add up all the numbers and divide by the number of numbers
(3+ 3+ 12+ 16+ 16+ 16+17+18+ 18+22+24+ 34+ 55)/13
254/13
19.53846154
mean = 19.54
The median is the middle number
Since there are 13 numbers the middle number is 13/2 = 6.5 which rounds to 7
The 7th number is 17
median = 17
Mode is the number that appears most often
16 appears 3 times which is more often than any other number
mode 16
The range is the largest number minus the smallest number
55-3 = 52
range = 52
