Question

If the outliers are not included, what is the mean of the data set?

72, 82, 3, 55, 62, 73, 90, 80, 151, 59, 46, 31

59
65
67
73

Answer 1

you have to add up all the numbers and divide that by how many numbers there are.
72+ 82+ 3,+55+ 62+73+ 90+ 80+ 151+ 59+ 46+ 31=804
804 divided by 12 numbers equals 67.
your mean is equal to 67.
