Chapter 2 Graphical methods for presenting data
Graphical methods for presenting data 2.1 Introduction We have lookedatways of collectingdataand thencollatingthem intotables. Frequency tables are useful methods of presenting data; they do, however, have their limitations. With large amounts of data graphical presentation methods are often clearer to understand. Here, we look
