If they represent the sample, then use the sample standard deviation formula √ [ 1/(n-1) ∑(xi - sample mean)2. If they represent the population, then use the population standard deviation formula √ [ 1/n ∑(xi - population mean)2. What are Standard Deviation Formulas for Ungrouped ...
Standard deviation formula If you’re wondering what the complete equation is to calculate the standard deviation, as described above, then the below image shows the standard deviation formula for a sample and a population. You’ll notice a slight difference between the two formulae; specifically,...

Standard deviation is the measure of the dispersion of the statistical data. Learn the definition of standard deviation and variance, formulas along with the solved examples.
Standard deviation = √(51 − 54.2)2+ (38 − 54.2)2+ (79 − 54.2)2+ (46 − 54.2)2+ (57 − 54.2)2/ (5 - 1) = 15.5 Therefore, mean = 54.2, and standard deviation = 15.5 Example 2: Find the mean and standard deviation for the following set of data: {1, 6, 7, ...
The STDEV.S function uses the classic sample standard deviation formula as below: Pro Tip! For this formula: xrepresents each value of the sample x̅is the mean of all the values in the sample ∑is the sum of the expression nis the total number of values or data p ...
Mathematical formula of standard deviation: Where, S:Sample standard deviation. N:Number of observations. xi:Observed value of the sample item. x̅:Mean value of the observation. How to Calculate Standard Deviation? The steps to calculate Standard deviation are: ...
