WebPrecision is a term used to describe data from an experiment that has been repeated several times. If the experiment yields a tightly grouped set of data points, then it has high precision; the greater the scatter of data points, … WebFeb 9, 2024 · 3.7.3. Precision. The term precision is defined as the closeness of repeated individual measurements of an analyte under specified conditions. This term is demonstrating the repeatability and reproducibility of the method and expressed as the coefficient of variation (CV).

The average mass from each set of data is to be calculated. Also, …

WebAs the name suggests, biological variation is a source of variance in laboratory test results. These data are commonly expressed as percent coefficient of variation (CV) or relative standard deviation (RSD). Both terms are equivalent and are calculated by first converting variance to SD, dividing SD by the Mean value of the data set, and then ...
