Follow the below steps: First, calculate the Mean Calculate The Mean Mean refers to the mathematical average calculated for two or more values. There are primarily two ways: arithmetic mean, where all the numbers are added and divided by their weight, and in geometric mean, we multiply the numbers together, take the Nth root and subtract it with one.

Add up the squared deviations and divide this value with the total number of values. Calculating payments image by Christopher Meder from Fotolia.

In those cases, Data which are well deviated from the RSD are taken into account. In case of the reverse situation i. It generally gives the idea of actual forecasts within the given set of data. Regular standard deviation gives a fair idea about the distribution of scores around the mean average. For example, with a mean score of 50 and standard deviation of 10, most of the people would expect that most scores would lie in between 40 and 60 and that nearly all scores would fall between 30 and This has been a guide to Relative Standard Deviation Formula.

Here we discuss how to calculate Relative Standard Deviation along with practical examples. We also provide a Relative Standard Deviation calculator with downloadable excel template.

Here are some of the most common scenarios when it is recommended to use this formula:. Related: Learn About Being an Accountant. The formula for calculating the relative standard deviation is as follows:. In this formula, S stands for the standard deviation and x stands for the mean of the data being used. Following are the steps to calculate this formula to determine the relative standard deviation:.

The following are examples of how to calculate the relative standard deviation using different scenarios:. You want to determine the relative standard deviation of a set of numbers. The set of numbers includes the following values: 50, 47, 54, and You have already found the standard deviation for this set of numbers to be 2. To determine the relative standard deviation, you will first want to find the mean of the set. You can find the mean by adding together the four numbers and then dividing them by four the number of values in the set.

You will then divide by 4 to get This means that the mean of the sample is In this formula, S is equal to 2.
