Geometric mean

What does the following statement mean regarding Geometric mean: The arithmetic mean of the logarithm of the values exponentiated. — Preceding unsigned comment added by 45.249.238.225 (talk) 07:39, 14 July 2017 (UTC)

Not sure why you are asking me this question. Check Geometric mean page and, if you don't understand logarithms, check Logarithm page. Drbb01 (talk) 02:10, 15 July 2017 (UTC)

Accidentally found your profile and saw graduate degrees in both "psychometric methods and counseling psychology". I know both these degrees have a strong statistics background for research and psychological measurements purposes. I myself was in search of psychological measurement subject notes and only found some Italian ones, initial poor google translations showed statistics knowledge is required. When searching for what geometric mean was my eye caught on the equation and equations have a head swirling effect on me and my mind was stuck on the "product of values" and "sum of values" definition plus poor logarithm understanding made it seem exhausting. This is why...

Simply as I can: The arithmetic mean is what we generally call "the average." We have a set of numbers, add them up, and divide the total by the "number of numbers." The geometric mean is also an average, but instead of adding the numbers and dividing, we multiply them together, then take the root, with the root equal to the number of numbers. For example if we have three numbers, to get the geometric mean you multiply them together, then take the cube root. I hope that helps. Drbb01 (talk) 23:25, 17 July 2017 (UTC)
