Welcome to a Survey on Graphical Inference
This web site is designed to conduct a series of three surveys on graphical inference which will help us understand human perception of graphics for use in communicating statistics. In this experiment, you will be guided through each of the three studies:
examines the ability to differentiate curves shown on charts and graphs (13 questions, about 15 minutes to complete).
examines the ability to predict data by using your mouse to draw a trend line (12 questions, about 15 minutes to complete). You may want a computer mouse handy for this study!
examines graph comprehension of different types of charts and graphs (12 questions, about 15 minutes to complete).
Finally we would like to collect some information about you (age category, education, and gender).
