## Reading and Interpreting Charts

This is a web-based experiment that asks people to report values they see in a series of charts. There will be two blocks of charts with different questions for each block. There is a page between the two blocks of questions to help remind you of the question change. You'll also be asked some additional questions for verification purposes and for demographics. Participation takes between 15 and 25 minutes.
