Answer:
Mean = 4, Median = 3, Mode = 1
Explanation:
The mean is also the average. To find it you add all the numbers up and divide that by the # of numbers given.
Median is the middle number when all the numbers are written out numerically including the doubles
1 1 1 2 3 3 5 5 15
Mode is the number that appears the most
in this case it is 1
