Mean is also known as the average of the numbers. To find the
mean, you have to add up all the numbers and then you have to divide by how
many numbers there are.
For example, this is how you find the mean of the numbers:
59 64 52 41
Add 59, 64, 52, and 41
you get 216.
Divide 216 by 4. You get 54.
So the mean of these numbers if 54.
Hope it helps.
