It explains the purpose of data analysis—describing past and present trends, predicting future events, and supporting sound decisions—while outlining the chapter’s progression from tools for describing data to counting and probability, then distributions of data and random variables, and concluding with data interpretation examples.

In this limited review of data analysis, we begin with tools for describing data; follow with tools for understanding counting and probability; review the concepts of distributions of data, random variables, and probability distributions; and end with examples of interpreting data.  \n4.1 Graphical Methods for Describing Data  \nData can be organized and summarized using a variety of methods. Tables are commonly used, and there are many graphical and numerical methods as well. The appropriate typeof representation for a collection of data depends in part on the nature of the data, such as whether the data are numerical or nonnumerical.
