mode
range
median
mean (to the nearest whole number)

the median is 14 the range is 15 the mode is 14 and the mean is 12.7

Explanation:

for the median you put all numbers is order but least to greatest and figure out the middle number for range you take the smallest and the biggest number and subtract them for mode you use the most repeated number and for the mean you add all the numbers and divide by the total of numbers I hope this helped
