The range of these numbers, the difference between the highest and lowest of these numbers, is equal to 28-15 = 13.
mean=19.1 median=18 mode=18 range=10 there are websites all over that help with this stuff just Google how to find mode mean range and median and you will get tons of results
To find the range of a group of numbers, subtract the smallest from the largest. examples: * range of {6, 8, 12, 19, 27} is 27 - 6 = 21 * range of {5, -2, 1, 10, 18} is 18 - (-2) = 18 + 2 = 20
-15.
18
Between 11 and 21: 12, 14, 15, 16, 18 and 20.

It is: 21+18+15 = 54 and 54/3 = 18 which is the mean average
To find the range of a group of numbers, subtract the smallest from the largest. examples: * range of {6, 8, 12, 19, 27} is 27 - 6 = 21 * range of {5, -2, 1, 10, 18} is 18 - (-2) = 18 + 2 = 20
To find the mean of the numbers, first sum them up: 18 + 15 + 21 + 10 + 24 + 21 + 18 + 16 + 20 + 22 + 18 + 18 + 12 + 21 + 25 + 20 + 19 + 23 = 346. Then, divide this total by the number of values, which is 18. Thus, the mean is 346 ÷ 18 ≈ 19.22.
18/21 x 15 is 12 6/7
18
19
It is (21+15)/2 = 36/2 = 18
We can't answer that without knowing the set of numbers.

Easy to figure out: put all of the numbers in order from least to greatest. Find the number that occurs the most and that is your mode. Or if the answer is obvious just find the number that occurs the most in the set. In this case 18is the answer.
The range is 9 and 3.01 is the standard deviation.
