4. Objective Students will be able to… Interpret data based on the shape of a data distribution Choose the appropriate measures of center (mean or median) and spread (standard deviation or interquartile range) to describe the distribution. Interpret summary statistics for center and spread in the context of the data.

8. Homework Solutions: Comparing the data: The distribution of miles per gallon for cars is skewed to the right. Most cars have between 25 and 30 mpg in the city, with a few cars with as many as 40 mpg. The distribution of miles per gallon for SUVs is fairly symmetrical. In general, SUVs get fewer miles per gallon than cars. The mean for cars is 32.9 mpg in the city and for SUVs is only 16.6 mpg. There is more variability in miles per gallon for cars than for SUVs. Most SUVs are within 4 mpg of the average, whereas most cars are within 7 mpg of the average.
