Population, in this context, means an entire data set, rather than a sample (section) of it. If you’re trying to calculate standard deviation from a population data set, you’ll need to use the closely-related STDEV.P function (or the older STDEVP which, like STDEV, is no longer recommended). With no guarantees that Excel will continue to support STDEV in newer releases, however, it’s probably best to use STDEV.S to calculate the standard deviation from a data sample. There isn’t much difference between STDEV and STDEV.S, with both having the same arguments and working in the same way. However, while STDEV is perfectly suitable for the task, Microsoft has replaced it with a newer function: STDEV.S. Just like the SUBTOTAL function and other Excel functions, the STDEV function exists to serve a single purpose: to allow you to calculate standard deviation in an Excel formula. Using STDEV or STDEV.S in Microsoft Excel You can learn more about standard deviation (and how it differs from standard error) in this guide. This is standard deviation at work, letting you see the spread of values in a data sample or data set. However, what if there are outliers in the data? What if you wanted to determine the variance (the typical difference between the average height and the data set)? You could use the AVERAGE function to determine the average height-so far, so good. Let’s assume that you have a group of 10 people and you’re interested in learning what the average height of the group is. To help explain standard deviation functions like STDEV and STDEV.S in Excel, we’ll give you an example. What is the STDEV function and what is it used for?
