How do you find the mean of the data set 4, 3, 15, 11, 3, 8, 7, 5?

Back

Add all the numbers (4 + 3 + 15 + 11 + 3 + 8 + 7 + 5 = 56) and divide by the count of numbers (8). Mean = 56 / 8 = 7.

How do you find the median of the data set 4, 3, 15, 11, 3, 8, 7, 5?

Back

First, sort the data: 3, 3, 4, 5, 7, 8, 11, 15. The median is the average of the two middle numbers (5 and 7). Median = (5 + 7) / 2 = 6.
