A Relative Standard Deviation (RSD) Calculator is a tool used to determine the relative variability or dispersion of a dataset. The RSD is calculated by dividing the standard deviation of a dataset by its mean and expressing the result as a percentage.
The formula for calculating RSD is: RSD = (Standard Deviation / Mean) * 100.
For example, if a dataset has a mean of 50 and a standard deviation of 5, the RSD would be: RSD = (5 / 50) * 100 = 10%. Therefore, the RSD of this dataset would be 10%, indicating a relative variability of 10% around the mean value.
The RSD is used to compare the variability of different datasets, especially when their means are different.
