Question

What is difference between standard deviation and relative standard deviation

Answer 1

Answer:

The relative standard deviation (RSD) is often times more convenient. It is expressed in percent and is obtained by multiplying the standard deviation by 100 and dividing this product by the average. Example: Here are 4 measurements: 51.3, 55.6, 49.9 and 52.0.

Answer 2

Answer:

The relative standard deviation (RSD) is a special form of the standard deviation (std dev). ... As the denominator is the absolute value of the mean, the RSD will always be positive. The RSD tells you whether the “regular” std dev is a small or large quantity when compared to the mean for the data set.
