Chapter 3, Problem 56SE

Property Crime Rates The boxplot shows the property crime rate per 100,000 residents in the 50 states. The outlier is Delaware. The regions are the Midwest (MW). Northeast (NE), South (S), and West (W).

a. List the approximate median crime rates per 10,000 residents for the four regions; for example, the median for the MW is about 3000.

b. List the regions from lowest to highest interquartile range.

c. Why is the interquartile range a better measure of the variability for these data than the range is?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
