Relative Standard Deviation Calculator


In statistics and probability, the relative standard deviation is very helpful for comparing uncertainty in-between the varying absolute magnitude of different data set. In short, the relative standard deviation is also known as RSD.

The RSD is always measured in percentage. It can be done by simply dividing the standard deviation by mean and multiplying by 100. i.e with the formula,
