The figure shows population density (people per square mile) for all states of a certain country. The states are divided into four geographical regions: A, B, C, and D. Answer the questions below. D- 0 100 200 300 400 500 600 700 800 900 1000 1100 People per Square Mile Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations? OA. These data are fairly symmetric and do not have outliers, and the median and interquartile range provide more reliable information in these circumstances. B. Some of these data have outliers and/or are skewed, and the median and interquartile range amplify the effects of outliers and skewness. OC. Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers. OD. Some of these data have vastly different centers, and the median and interquartile range provide more reliable information in these circumstances. List the approximate median number of people per square mile for each location; for example, the median for Region A is approximately 220. The median for Region B is The median for Region C is The median for Region D is List the regions from lowest interquartile range (on the left) to highest.

People per Square Mile
Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations?
OA. These data are fairly symmetric and do not have outliers, and the median and interquartile range provide more reliable information in these circumstances.
B. Some of these data have outliers and/or are skewed, and the median and interquartile range amplify the effects of outliers and skewness.
OC. Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers.
OD. Some of these data have vastly different centers, and the median and interquartile range provide more reliable information in these circumstances.
List the approximate median number of people per square mile for each location; for example, the median for Region A is approximately 220.
The median for Region B is
The median for Region C is
The median for Region D is
List the regions from lowest interquartile range (on the left) to highest.
