Consider two completely different data sets: homework scores for a statistics class and IRSC student ages. The statistics class homework scores data set has a mean of 65 and a standard deviation of 15. The IRSC student ages data set has a mean of 22 and a standard deviation of 12. Calculate the Coefficient of Variation for both data sets. Round solutions to one decimal place, if necessary. Coefficient of Variation for the statistics homework scores data set: Coefficient of Variation for ages of IRSC students data set: Which data set has greater variability? Select an answer Thus, we see that when comparing two data sets, the data set with the larger standard deviation Select an answer | necessarily have greater variabilty
