They indicate the skill levels of the employees. The following are the employee scores of an organization. Let us consider an example to understand the concept of standard deviation in Excel. Calculating Standard Deviation in Excel #1 – Calculate Population Standard Deviation in Excel Note: The STDEV.S is available in Excel 2010 and the subsequent versions. The logical value “false” is counted as 0 and “true” is counted as 1. The STDEVA function calculates the standard deviation by counting the text values as zero.The “S” of the function represents the sample data set. The STDEV.S function calculates the standard deviation Standard Deviation Standard deviation (SD) is a popular statistical tool represented by the Greek letter 'σ' to measure the variation or dispersion of a set of data values relative to its mean (average), thus interpreting the data's reliability.
The two functions are explained as follows: Note: The sample standard deviation helps make conclusions for the population. A sample of the population is taken when it is difficult to use the complete data set. The population refers to the whole data set.The population and sample are defined as follows: Otherwise, it returns the “#DIV/0!” error. Note 2: The sample standard deviation formula works correctly when the supplied arguments contain at least two numeric values. Note 1: If the entire sample data is entered as a range, the “number 2” argument becomes optional. “Number 1” is mandatory and “number 2” is an optional argument. Number 2: This is the second value of the sample data.
Number 1: This is the first value of the sample data.The function accepts the following arguments: The syntax of the function is stated as follows: The functions STDEV.S, STDEVA, STDEV, DSTDEV are under sample and STDEV.P, STDEVP, STDEVPA, DSTDEVP are under population. These are grouped under sample and population. In excel, there are eight formulas to calculate the standard deviation. Source: Standard Deviation in Excel () Standard Deviation Formulas in Excel

In Excel, the STDEV and STDEV.S calculate sample standard deviation while STDEVP and STDEV.P calculate population standard deviation. The standard deviation shows the variability of the data values from the mean (average).
