The Role of Visual Displays of Data
As you read in your textbook reading in this unit, visual displays of data are critical to ensure that the fundamental structure of data is understood. If data are only presented in a summarized, narrative form, misinterpretation can result. Let us look at an example of how this could happen.
Consider the following hypothetical scenario:
A recently-published study found that 76 percent of smart phone users prefer free, ad-supported apps over ones that need to be purchased. This percentage is up from 56 percent a year ago. In addition, the study reports that only 15 percent of smart phone users prefer to pay for ad-free apps; this is down from 32 percent a year ago.
In your initial post, explain which charting method you would select to display these data and why.
