laikas RT @shamsha: need help: can someone plz describe coefficient of variance in English? thnx!
Some people obviously can:
@HCIR_GeneG: It's a measure of variability of a data sample, without paying attention to absolute values. Can be used to compare diff. distributions.
@flutesUD: CV = Std Dev / Mean. Tells u how variable the data are regardless of their units. Lets u compare across different types of studies.
DrVes@laikas @shamsha Check the Wikipedia definition, click on the links in the description and you'll get there... :) http://bit.ly/18NnEH
In probability theory and statistics, the coefficient of variation (CV) is a normalized measure of dispersion of a probability distribution. It is defined as the ratio of the standard deviation to the mean .
