Creating graphs gives you a picture of your data. In our visual-oriented world, graphing data is one way of "letting the statistics speak for themselves." The proper choice of graph depends on the nature of the variable. Most graphs are pie charts, bar graphs, histograms, frequency polygons or timelines. There are others, but in these are the graphs you will see most often in media, public opinion polls and research studies. A histogram usually has vertical bars placed on the horizontal axis (x-axis) that touch each other, although some texts no longer require that the bars touch. The y-axis shows the frequency, percetage or rate of occurrence. Figure 1.
