coefficient of variation for variability which measure is better for quartile variation which of the following is used as a measure of variability for predicting skewed data? how does sd/m measure the relative variability of a variable which of the following measures is used to measure variability of sleep when dividing a data type by a quartile deviation why qn for rem what is the coefficient of variation what is the coefficient of variation how to do the measure of the variability of a variable? what to use for the coefficient of variation what coefficient of variation is used to describe relative variability of multiple variables which of the following is a relative measure of a variable's variability? covariance what coefficient of variation is used to determine variation when dividing the coefficient of variation by the median it would be more appropriate to use the coefficient of quartile variation or covariance in the calculation of the variance? what is the coefficient of variation for each quartile? which measure is best to measure relative variation how to use sd/m for variability what is the coefficient of variation when calculating a variable's relative variability
