In an iron determination from the same amount of sample, the five replicate results were obtained: 20.1, 19.6, 20.0 and 19.9 and 20.4 mg iron.
Calculate the standard deviation, variance, standard deviation of mean, coefficient of variation and relative standard deviation in ppm of the given data.
First, we list the data points: 20.1, 19.6, 20.0, 19.9, and 20.4 mg. Step 1: Calculate the mean ((\bar{x})) [ \bar{x} = \frac{20.1 + 19.6 + 20.0 + 19.9 + 20.4}{5} = \frac{99.9}{5} = 19.98 , \text{mg} ] Step _________ _____ ______ ____ _________ _____ ___.
