Figure the mean, median and standard deviation for the number of words learned by seven infants. I beleive the mean is 45.5 and the median is 10.The numbers are 10,12,8,0,3,40,and 18.

Answer 1

How can the mean be much more than any of the numbers?

10 + 12 + 8 + 0 + 3 + 40 + 18 = 91
91/7 = 13

The median is 10.
