How do you find the mean of these numbers: 2, 57, 38, 42, 6?

Back

Add the numbers: 2 + 57 + 38 + 42 + 6 = 145. Then divide by the count of numbers (5): 145 / 5 = 29.

Front

How do you find the median of these numbers: 1, 2, 2, 8, 9, 14?

Back

First, sort the numbers (they are already sorted). Since there are 6 numbers (even), the median is the average of the 3rd and 4th numbers: (2 + 8) / 2 = 5.

If a set of numbers is 16, 5, 7, 12, how do you calculate the mean?

Back

Add the numbers: 16 + 5 + 7 + 12 = 40. Then divide by the count of numbers (4): 40 / 4 = 10.
