Answer:
mean: 10.4
mode: 14
median: 13
range: 11
Explanation:
To find a mean, add up all the numbers of the data set and divide them by the number of numbers.
To find a mode, just search for the number used the most in the data set.
To find a median, search for the number right in the middle of the data set (if there are 2 numbers in the middle, the median is the average of those 2 numbers.)
To find a range, order all the numbers of the data set from lowest to highest. Then subtract the lowest number from the highest number. :)
