Chapter 4 - Displaying and Summarizing Quantitative Data - Exercises: 12

Answer

a. From the histogram, we expect the mean to be greater than the median as the distribution is skewed to the right. b. The distribution is right skewed. The center is about 3, and the data is spread between 1 and 21, with 21 as an outlier. c. The median would be an appropriate measure for this distribution as the distribution of data is not symmetric.
