In this series of blog posts, we will use a survey by the U.S. law firm Winston & Strawn to learn about survey methodology. In 2013 the firm produced a 33-page report based on the survey results entitled “The Winston & Strawn International Business Risk Survey 2013”. To download a PDF of the report, click here.
The plot in the image below comes from page 18 of the report. The survey had asked respondents the question stated in the header, given them eight choices, and this plot presents the results as a graph. Here we will focus on one aspect of that plot: how effectively it presents the sum of the number of times respondents selected each of the risk choices.
Notice that the plot identifies the number of companies selecting a risk by three methods. One is the horizontal x-axis that ranges from zero on the left to 80 on the right. For example, “Rogue employees” is just to the left of the 50 marker on the x-axis so a reader could estimate 47-49 respondents chose if from that bar’s end point, where it reaches on the x-axis, and the figure from the y-axis.
