This study is intended to assess how people perceive statistical graphs and charts, and how charts are used to make decisions.
If you are 18 years of age or older (19+ in Nebraska and Alabama, 21+ in Mississippi), and have normal or corrected-to-normal vision you may participate in this research.
Statistical charts and graphs are everywhere – in news articles, advertisements, and on TV. We are interested in whether people read information from charts accurately, and whether certain types of charts are more useful when making data-informed decisions. Unfortunately, we know relatively little about how people read and perceive charts. This study is designed to address this gap in research by systematically investigating the use of charts in different tasks and contexts.
In order to participate you must be 18 years of age or older (19+ in Nebraska and Alabama, 21+ in Mississippi) and have normal or corrected-to-normal vision.
Participation in this study should require less than 30 minutes of your time. You will be asked to look at statistical charts and then answer questions based on the visualization.
We expect that each of these tasks will take less than 1 minute to complete. We will start out with a practice question so that you can become accustomed to the interface. After the practice task, there will be a series of questions.
Participation will take place in a location of your choosing, on your computer. We ask that you use a computer or tablet with a screen resolution of at least 1024x768 (most moderately sized tablets meet this standard).
