Statistical Mean: Learn

The statistical mean is commonly called the average.

It is a common measure of central tendency, along with median and mode.

To find the mean of a group of numbers:

  • Add the numbers together
  • Divide by how many numbers were added together

Example: The average of the numbers 1, 2, 6, 7 and 9 is
(1 + 2 + 6 + 7 + 9) / 5
= 25 / 5
= 5
