An example of choosing the wrong chart 1o present variables h(' Uo The issue in Figure 4a most clearly demonstrated is that the sections of the pie chart total 100%. Pie charts should total 100%, but the sections don't in Figure 4b. However, the pie chart in Figure 4b is problematic because not only do the percentages not equal 100%, but also the choice to represent multiple vanables (three different studies) through a pie chart is naccurate. A pie chart shows the relationship between different parts of a whole. In the case of Figure 4b, the visual shows the relationship between one part of three wholes (i.e., one variable in three different studies). A better choice for a survey with variables is the bar chart on the right, which shows the relationship between variables. The bar chart demonstrates variables in the easiest way for the reader to understand. Making sure you pay attention to these types of issues can help you better use your time and create images that ethically support your argument in your reports.
