Question

Give formula for Relative 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:

$CV = \frac{\sigma}{\mu}$

$\sigma =$

population standard deviation

$\mu =$

population mean

(S x 100)/x = relative standard deviation

• Calculate the mean of the numbers in the data you are working with. Subtract the mean from each number in the data to determine the deviation for each number. Square the deviations for each number. Add together the squared deviations
