Geometric mean refers to the nth root value of the product of n numbers. It signifies the central value of a set of positive numbers by calculating the product of their values with suitable power raised for the product. The geometric mean of two numbers, x and y, is equal to the length...
The geometric mean should be used when working with percentages, which are derived from values. The geometric mean is a very useful tool for calculating portfolio performance. It is because it takes into account the effects of compounding. The formula for Geometric Mean The geometric mean is used...
What is the Definition of Mean? Mean, one of the important and most commonly used measures of central tendency is the average or a calculated central value of a set of numbers. The process of calculating the mean is different based on the type of data (grouped or ungrouped data). ...
Frequency Distribution or Continuous Series: Firstly, we need to find out the Modal class. Modal class is the class with the highest frequency. Then we apply the following formula for calculating the mode: Mode = l + hf1−f0(2f1−f0−f2) Where, Solved Example Calculate the Average ma...
There are two main steps to calculating the geometric mean:Multiply all values together to get their product. Find the nth root of the product (n is the number of values).Before calculating this measure of central tendency, note that:The geometric mean can only be found for positive values....
What is the Formula For Scale Factor?The basic formula that is used for calculating the scale factor is, Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure ...

The geometric mean, unlike the arithmetic means, is used for calculating growth rates. This is because growth rates are expressed as percentages and not absolute values. Because of this, it is most often used in business and finance for calculating things such as portfolio returns and stock inde...
Sometimes the phone transmission goes even up to 3.4 kHz. The HiFi range goes fromf1= 20 Hz tof2= 20000 Hz. The correctcenter frequency isf0= 632.5 Hz (!) as geometric meanand not the value 10.01 kHz of the arithmetic mean calculation. Look here: ...
A simple method for calculating a risk-adjusted CAGR is to multiply the CAGR by one minus the investment’s standard deviation. If the standard deviation (i.e., its risk) is zero, then the risk-adjusted CAGR is unaffected. The larger the standard deviation, the lower the risk-adjusted ...
