Answer:
range: 6
median: 13
mode: 12 & 14
mean: 12.6
Step-by-step explanation:
the range of data is just the largest number subtracted by the smallest number
the largest number is 16 and the smallest 10
16 - 10 = 6
the range is 6
the median is the middle number in a set of data. to find this, you would write the list in numerical order and and cross a number off from each side until you reach the middle number
the median is 13
the mode is the number that appears most frequently. looking at the data, that seems to be both 12 and 14, both occuring 7 times
the mode is 12 and 14
the mean of a range of data is when you add up all the numbers, and divide by the amount of numbers in the data set.
adding the numbers together, we get 391, and we divide that by the amount of numbers in the data set, which is 31
391/31 = 12.6
the mean is 12.6
