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.
The mean is the average of a set of numbers Mean/average = sum of the numbers in the set divided by the amount of numbers in the set
mean means the average or all the numbers in the set added together and then divided by the number of numbers in the set of numbers.
Mean = Total of the numbers / n So total of the numbers = n*mean
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.
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.
