Find the coefficient of variation for each of the two sets of data, then compare the variation. round results to one decimal place. compare the variation in heights to the variation in weights of thirteen-year old girls. the heights (in inches) and weights (in pounds) of nine randomly selected thirteen-year old girls are listed below. hint: use minitab to compute the mean and standard deviation of each set. then, compute the coefficient of variation, which is defined as the ratio written in percent notation.
