ABSTRACT
In addition to representing data in tabular and graphical forms, a key way to describe data is to use, fittingly enough, descriptive statistics. By examining just a few descriptive statistics for a variable’s scores, we can get a very good idea about where the center of those scores lies, how far the scores are from this center, and what shape the distribution of the scores takes. In this chapter, we’ll cover several descriptive statistics that are used for various types of variables: ratio, ordinal, and nominal. We’ll start with the ratio level.
