Question 8

0 / 0.5 pts

The Lee family is looking to buy a house in one of two suburban areas just outside a major city, and the air quality is a top priority for them. One suburb advertises use of hybrid cars and solar panels, while the other area focuses on its convenient bus routes and availability of Hummer dealerships. Is the mean or median the better measure to use for deciding which area has better air quality? (Hint: both these populations are skewed.)

1. median, because it is always the best measure of central tendency in any population

2. mean, because it is always the best measure of central tendency in any population

3. median, because it is less biased by skewness being dependent on the middle score

4. mean, because it represents the balance of the distribution

Explanation / Answer

3) Median should be used  because it is less biased by skewness being dependent on the middle score. It gives a better idea of the average tendency of air quality.
