The geometric mean return represents the growth rate or compound rate of return on an investment. B is incorrect. The harmonic mean may be viewed as a special type of weighted mean in which an observation’s weight is inversely proportional to its magnitude. The harmonic mean is a relatively...
Mean is a statistical term used to explain a set of numbers and has three forms. You can calculate the arithmetic mean, geometric mean, or harmonic mean. For this tutorial, we’ll explain how to calculate thearithmetic meanwhich is known in math as the average. ...

Do I calculate the annual average by simply summing all 12 monthly data points (i.e. monthly indices) and divide by 12; or should I be using the geometric mean here? From Wikipedia I see that This makes the geometric mean the only correct mean when averaging normalized result...
Among the choices, thegeometric average(also known as the "compound average") does the best job of describing investment return reality. To illustrate, imagine that you have an investment that provides the followingtotal returnsover a three-year period: ...
Understanding the Geometric Mean The geometric mean, sometimes referred to ascompounded annual growth rateortime-weighted rate of return, is the average rate of return of a set of values calculated using the products of the terms. What does that mean? The geometric mean multiplies several values...
