Most of this book, as is the case with most statistics books, is concerned with statistical inference , meaning the practice of drawing conclusions about a population by using statistics calculated on a sample. However, another type of statistics is the concern of this chapter: descriptive statistics , meaning the use of statistical and graphic techniques to present information about the data set being studied. Nearly everyone involved in statistical work works with both types of statistics, and often, computing descriptive statistics is a preliminary step in what will ultimately be an inferential statistical analysis. In particular, it is a common practice to begin an analysis by examining graphical displays of a data set and to compute some basic descriptive statistics to get a better sense of the data to be analyzed. You can never be too familiar with your data, and time spent examining it is nearly always time well spent. Descriptive statistics and graphic displays can also be the final product of a statistical analysis.

In addition, you are identifying public health actions that might be needed to eliminate or prevent exposures, or you are identifying critical data gaps. This chapter describes the process by which you, with the input of the site team, take the findings of exposure and health effects evaluations and draw conclusions regarding the degree of public health hazard, if any, posed by the exposure situations you have studied at a site Section 9. An overview of the process is shown in Figure In addition, guidance is provided for developing recommendations and a PHAP that will help ensure that needed follow-up actions are achieved.
