Are you guys searching for a best tool that gives Relative Standard Deviation of data setIf yes then you are the correct place. If data set have high standard deviation than the values are spread out very much.

The standard deviation is the average amount of variability in your dataset. Values must be numeric and may be separated by commas spaces or new-line. It is calculated using the following equation which can look intimidating but can be broken up into smaller steps that are easier to understand. This is a common term in mathematics and Statistics which is utilized in experiments and industrial testing in the real world.

To calculate standard deviation start by calculating the mean or average of your data set. Standard deviation sigma The standard deviation denoted by the greek letter sigma sigma is a measure of how much a set of numbers varies from the mean mu. Therefore the calculation will be like this. In most cases you will find yourself using the sample standard deviation formula as most of the time you will be sampling from a population and wont have access to data about the whole population.

Next add all the squared numbers together and divide the sum by n minus 1 where n equals how many numbers are in your data set. Standard Deviation Calculator. Relative Standard Deviation Calculator. In other words it defines how the whole elements or members in the sample deviates from its mean in the statistical surveys or experiments.
