Coefficient Of Variation Interpretation. While interpreting coefficient of variation, 0 can be reported provided it actually implies zero. for example, zero weight implies no weight. The coefficient of variation (cv), also known as “relative variability”, equals the standard deviation divided by the mean. In this case, blood pressure and pulse rate are two different variables. Suppose we have another investment, say, y with a 1.5% mean monthly return and standard deviation of 6%.

To interpret its value, see which of the following values your correlation r is closest to: The term “coefficient of variation” refers to the statistical metric that is used to measure the relative variability in a data series around the mean or to compare the relative variability of one data set to that of other data sets, even if their absolute metric may be drastically different. What is coefficient of variation. Interpreting the coefficient of variation. The coefficient of variation (cv) also known as relative standard deviation (rsd) is the ratio of the standard deviation(σ) to the mean (μ). More specifically, r 2 indicates the proportion of the variance in the dependent variable (y) that is predicted or explained by linear regression and the predictor variable (x, also known as the independent variable).
For example, if we had data on students’ sat scores and high school grade point.
The cv or rsd is widely used in analytical chemistry to express the precision and repeatability of an. The coefficient of variation (cov) is a measure of relative event dispersion that�s equal to the ratio between the standard deviation and the mean. In statistics it is abbreviated as cv.
