Lesson: 21: Statistics
Topic: Arithmetic Mean
Domain: Statistics

The mean is the total shared out equally, so it is the sum divided by how many there are. It can be a value nobody actually has.

Study Tip

One extreme value drags the mean a long way. Five wages of 10000, 11000, 12000, 11000 and 96000 have a mean of 28000, which is more than four of them earn.
