Consider two completely different data sets: price per gallon of gas in Fort Pierce and SAT scores of students at a certain high school. The price per gallon of gas data set has a mean of $2.48 and a standard deviation of $1.15. The high school SAT scores data set has a mean of 1100 and a standard deviation of 179. Calculate the Coefficient of Variation for both data sets. Round solutions to one decimal place, if necessary. Coefficient of Variation for the price per gallon of gas data set: % Coefficient of Variation for high school SAT scores data set: % Which data set has greater variability? Thus, we see that when comparing two data sets, the data set with the larger standard deviation necessarily have greater variabilty.
