![]() ![]() ![]() Higher standard deviation values indicate that the data is spread out, while a lower standard deviation indicates that the values are centered around the mean or average of the dataset. Type the STDEV function in an empty cell.Ĭalculating standard deviation in Google Sheets is very easy. When using single values, there must be a minimum of two. The function can be used on single values or arrays. Values can be typed or in the form of cell references. To calculate the standard deviation of a sample, you can use the STDEV function: STDEV(value/array1, value/array2*). How to Calculate Standard Deviation in Google Sheets with the STDEV Function? The STDEVA and STDEVPA functions assume that cells with text are equal to a value of 0. Like DSUM, these functions work with data structured as database-like tables.įinally, there is another version of these formulas to be used on datasets that may contain text values in some cells, such as a dash or other characters to represent zero. In addition to providing both of the formulas described above as built-in functions - STDEV for samples and STDEVP for populations - Google Sheets features some additional versions, all with the same syntax and parameters.įor example, both formulas are also available as database functions: DSTDEV and DSTDEVP. If you have a sample of the population, you should use the sample version. If you have access to the data for the entire population, which isn’t often the case, you should use the population version of the formula. ![]() The choice between the two depends on the type of dataset you’re working with. To calculate the standard deviation for a sample of the population, use the following formula: s = √Σ( x i - x̄)^2/(n-1) The formula used to calculate the standard deviation for a population is as follows: σ = √Σ( x i - μ)^2/N To calculate the standard deviation of a dataset, you need to sum the square of the differences between each value and the mean, then divide by the size of the dataset (population) or the size of the dataset minus one (sample). How to Find Standard Deviation in Google Sheets? You have step-by-step instructions on how to use the functions with different types of data and in combination with other functions. You will learn the differences between the multiple versions of the STDEV function, like STDEVP, STDEVA, STDEVPA, DSTDEV, and DSTDEVP. In this guide, you will learn how to calculate standard deviation and review all the built-in functions available to calculate it for you in Google Sheets. The formula used to calculate it is straightforward, but if you use a spreadsheet program like Microsoft Excel or Google Sheets, there are many built-in functions that will calculate it for you. In other words, a low standard deviation indicates that most of the values are close to the mean or average of the dataset, while a high value indicates that the values are spread out over a wider range. It shows the spread of the data by calculating the average distance of values to the dataset’s mean, regardless of whether they are above or below it. Standard deviation is one of the main measures of dispersion in a dataset. ![]()
