A few years ago, the wedding registry website, theknot.com, wrote that, "The mean cost of a wedding is $28,000, while the median cost is $8,000." They used customers for the year as the data for both of these statistics. Why is there a difference between these two statistics? Select one:
a. The two statistics used different populations.
b. The two statistics are calculated differently and can never be the same number.
c. One number is a parameter, and the other number is a statistic.
d. The mean is pulled up by some expensive weddings, while the median is not.
e. None of the above are correct.
