Answer: B. HUD used the median because the data are skewed right.
Step-by-step explanation: If you use the mean, houses that are extremely expensive (which are generally a few) can affect the average and show house values that are not realistic (most likely higher than the real average). The median, however, is a value of equal probability. As an example, 4 houses are for sale at $100,000, 200,000 and 1,000,000. The average = $433,000. The median is $200,000 (a more realistic value).
