The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude? CV = = Standard deviation . 100% Heights | Weights Mean 75 178 79 226 CV heights = % (Round to the nearest tenth as needed.) 71 189 74 178 CVweights = % (Round to the nearest tenth as needed.) 70 193 73 205 What can you conclude? 66 198 72 209 O A. Weight is more variable than height. 70 208 O B. Height is more variable than weight. 79 221 74 179 68 193
