Use our relative standard deviation calculator to find the RSD for a set of data. Plus, learn the formula and steps to find it.

The RSD is sometimes used for convenience but it can also give you an idea about how precise your data is in an experiment. The more precise your data, the smaller the RSD.

You can use the online calculator to calculate the relative standard deviation of the data set.

Aug 15, 2024 · To find the relative standard deviation of a range, first find the standard deviation (using the STDEV function), divide it by the range's average, and then multiple the result by 100.

Relative Standard Deviation Calculator (High Precision) - Calculate the relative standard deviation of a set of numbers.

Lastly, to find the Relative Standard Deviation (RSD), divide the standard deviation by the mean and multiply by 100 to express it as a percentage: RSD = (2.83 / 14) x 100

Jun 6, 2025 · In this article, we will discuss the definition of relative standard deviation, when this formula is most appropriately used and the steps you can use to calculate relative standard deviation.

Sep 19, 2024 · By dividing the standard deviation by the mean and expressing it as a percentage, we create a relative measure that allows for meaningful comparisons across different scales and units. …

Dec 8, 2025 · Enter the mean and standard deviation of a data set into the calculator to determine the relative standard deviation. The following equation is used to calculate the relative standard deviation …

Jul 23, 2025 · Relative standard deviation is defined as a percentage standard deviation that calculates how much the data entries in a set are distributed around the mean value.
