For the following sample, answer the following: Remember you can copy and "paste special" the table into the Excel sheet. Here is a sample of the cost of new cars. 34000 31000 37000 28000 27000 38000 39000 29000 40000 25000 26000 30000 Here is a sample of grades on a test. 63 66 84 30 85 89 83 34 79 96 87 71 What is the mean of the car costs? The standard deviation tells you how spread out the scores are. What is the sample standard deviation of car costs? The coefficient of variation tells you how spread out the scores are, relative to the average. The coefficient of variation is calculated by dividing the standard deviation by the mean. What is the sample coefficient of variation of car costs?
