Estimation of sampling and analytical uncertainties using Excel Data Analysis toolpak
In the previous blog https://consultglp.com/2018/08/22/a-worked-example-of-measurement-uncertainty-for-a-non-homogeneous-population/ , we used the basic ANOVA principles to analyze the total chromium Cr data for the estimation of measurement uncertainty covering both sampling and analytical uncertainties….
In selecting random samples for analysis, it is necessary to generate random numbers. Random numbers also are used for simulations and can be used to create sample datasets. Random numbers can be generated in a number of different ways ……
We have been talking about the importance of carrying out random sampling for laboratory analysis. What is actually randomization?
