Question

Find the mean of the following data set: %0D%0A%0D%0A 4, 1 , 1 , 7 , 5 , 2, 8

Answer 1

To find the mean of a data set, we add up all the numbers in the data set and divide the sum by the total number of values.

Adding up the numbers: 4 + 1 + 1 + 7 + 5 + 2 + 8 = 28

The total number of values is 7.

So, the mean is: 28 / 7 = 4.
