The "mean" of a group of numbers is their "average". It doesn't tell you what the numbers are, or even how many numbers there are.
No, the geometric mean is not the same as the mean of two numbers.
Given a set of numbers, and its mean, we can find the difference between each of the numbers and the mean. If we take the mean of these differences, the result is called the mean deviation of the numbers.
Mean = Total of the numbers / n So total of the numbers = n*mean
To take the mean of a set of numbers is just to take the average of the set of numbers. Add all the numbers together and divide this total by the amount of numbers you had. This is the mean.
