CV - Coefficient of Variation Calculator is the online statistics tool for data analysis specifically programmed to find out the values of number of inputs, Mean, Standard Deviation and Variance Coefficient with respect to the input values of data set
Definition
The normalized measure of dispersion of a probability distribution is called as coefficient of variation as often abbreviated as CV. In probability theory and statistics, it is also known as unitized risk or the variation coefficient. The CV is derived from the ratio of the standard deviation to the non-zero mean and the absolute value is taken for the mean to ensure it always positive. It is sometimes expressed as percentage, in which case the CV is multiplied by 100
Coefficient of Variance Formula
The Equation or Formula to find out the Coefficient of Variation is given below
Coefficient of Variation C_{v} = Standard Deviation / Mean
The standard deviation of data must always be understood in the context of the mean of the data therefore the coefficient of variation is useful. The coefficient of variation is a dimensionless number. So when comparing between data sets with different units or widely different means, one should use the coefficient of variation for comparison instead of the standard deviation
The collection of tools employs the study of methods and procedures used for gathering, organizing, and analyzing data to understand theory of Probability and Statistics. The set of ideas which is intended to offer the way for making scientific implication from such resulting summarized data. To make your coefficient of variation calculation easy, this Online Calculator can help you to find out the number of inputs, mean, standard deviation and variance coefficient values with respect to the inputs given
