STDEV: Same as STDEV.S but used in spreadsheets created in Excel 2007 or earlier.STDEVA: Standard deviation of a dataset including text characters like “False” or 0.STDEV.S: Standard deviation of a numeric dataset.The six standard deviation formulas available in Excel include:

In most cases, it isn’t possible to use data from an entire population (such as measuring metabolic rate in females), so it’s much more common to use sample standard deviation and then infer the results across the entire population.

Population standard deviation: Uses all datasets from the entire population.

Sample standard deviation: Uses a single dataset from a sample of a larger population.

There are two forms of standard deviation you can calculate in Excel. Regardless why you may need to calculate the standard deviation of a dataset, Excel makes it extremely easy to do so.

How To Calculate Standard Deviation In Excel

Financial risk: Stock analysts use standard deviation to measure how much the value of stocks or other assets vary, which can indicate whether an investment is risky or not.

Industrial quality: Measuring whether the size or quality of a product that comes off a production line varies can indicate how well that machine is producing a product within acceptable specifications.

Scientific evidence: Measurements across experiments with results that vary less from the mean usually indicate stronger evidence than measurements that vary wildly.

Population studies: Health researchers may not only be interested in determining the difference in metabolic rates between men and women, but also how much those rates vary between those two groups.
