Descriptive Statistics

There are two major branches of statistics in an elementary statistics course: descriptive statistics and inferential statistics. Descriptive statistics involves describing the data that is available while inferential statistics involves drawing conclusions about a population based on a sample.

The purpose of this site is to help a student understand the different kinds of descriptive statistics. Understanding means more than just knowing how to find the numerical values, it also includes knowing when each measure is appropriate to use.
