The calculation of Coefficient of Variation (CV) from duplicate measurements made on a number of different subjects or materials is used to determine the reproducibility of the measurements as an alternative to making a large number of observations on a single subject or material to estimate the within-run imprecision directly (Jones & Payne 1997). Logical Tests in Excel. You can use anything as a logical test provided Excel can determine whether the outcome is TRUE or FALSE. Some examples of logical tests that you can use with the IF function include: C5=C6 (compare cell C5 to C6. If they are equal, the outcome is TRUE, otherwise the outcome is FALSE).
