Statistical Functions in Excel If the value received is on the higher side then that means that your data has a lot of fluctuations and vice versa. To calculate standard deviation in excel we use STDEV function. In the same example we shall use the STDEV function so our formula will be =STDEV(B2:B12). Our answer is around 20 which indicates that the marks of the students fluctuates a lot.

How to Use the STDEV.S Function in Excel The standard deviation is a measurement of dispersion of a set of data. In other words, it tells us how spread out a set of data is. Similarly to using other formulas in statistics, the calculation of a standard deviation is a fairly tedious process to do by hand.

Calculate Standard Deviation The standard deviation formula is similar to the variance formula. It is given by: σ = standard deviation. xi = each value of dataset. x (with a bar over it) = the arithmetic mean of the data (This symbol will be indicated as mean from now) N = the total number of data points.
