This interactive project is based on one of our own theoretical pieces. But see how much you can tell just by the graph, before you turn to the actual piece on which it was used.

Click on any of the question numbers for jeanne's lecture notes on that question.

1. Can you guess what the variables might be on this graph?

2. How would you explain interaction on this graph?

3. What do you suppose the relative size of the areas represents?
