Zip codes

Zip codes revisited. Here are some summary statistics to go with the histogram of the zip codes of 500 customers from the Holes-R-Us Internet Jewelry Salon that we saw in Exercise 49:

a) Is the mean or median a better summary of the center of the zip code distribution? Why?

b) Is the standard deviation or the IQR a better summary of the spread? Why?

c) What can these statistics tell you about the company’s sales?

Exercise 49:

Zip codes. Holes-R-Us, an Internet company that sells piercing jewelry, keeps transaction records on its sales. At a recent sales meeting, one of the staff presented a histogram of the zip codes of the last 500 customers, so that the staff might understand where sales are coming from. Comment on the usefulness and appropriateness of the display
