WebWe'll jump right in with a formal definition of the covariance. Covariance Let X and Y be random variables (discrete or continuous!) with means μ X and μ Y. The covariance of X … In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage, and is defined as the ratio of the standard deviation to the mean (or its absolute value, ). The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an assay. It is also commonly used in fields such as good body language in interviews https://spencerslive.com
