How to calculate 2 standard deviations in excel

The mean represents the average value in a dataset. It gives us a good idea of where the center of a dataset is located.

The standard deviation represents how spread out the values are in a dataset.

It gives us an idea of how closely the observations are clustered around the mean.

Using only these two values, we can understand a great deal about the distribution of values in a dataset.

To calculate the mean of a dataset in Excel, we can use the =AVERAGE(Range) function where Range is the range of values.

To calculate the standard deviation of a dataset, we can use the =STDEV.S(Range) function, where Range is the range of values.

This tutorial explains how to use these functions in practice.

Technical Note

 

Both the STDEV() and STDEV.S() function calculate the sample standard deviation. 

 

You can use the STDEV.P() function to calculate the population standard deviation if your dataset represents the entire population of values.

 

However, in most cases we’re working with sample data rather than an entire populatio
