Introduction

So now that we have discussed some methods for collecting data we can look at what to do with those findings. Whether you have collected categorical or numerical data you will want to choose an appropriate type of graphical display so that you can see the data. Charts and graphs of various types, when created carefully, can provide important information about a data set. You will also need to analyze the data with numerical and summary statistics. Once you have constructed a graphical display and have calculated numerical statistics, it will be necessary to describe your findings verbally. Statisticians, such as yourself, then make appropriate conclusions and comparisons based on the data and statistics, avoiding opinions and judgment statements. This chapter will concentrate on some of the more common visual presentations of data, numerical analysis of data, and verbal descriptions of data.
