ABSTRACT
As you learned in the previous chapter, the mean is the balance point in a distribution-that is, it is the point at which the deviations below the mean balance (or cancel out) the deviations above the mean. Although the mean is the most popular average, there are two conditions under which it should not be used: (1) when a distribution is clearly skewed, and (2) when the data are not equal interval. In this chapter, you will learn about two alternative averages that can be used when the mean is inappropriate.
