Before you start your visualizations, sketch some examples of what the picture would look like IF things were the way you would like them to be.



The impression from the ladder graph is derived from the idea that if things are the way you would like them to be:
The change for the control/comparison group is due to (a) measurement noise and (b) experience with the measure. Whereas the treatment should add change effects in a desired direction.

Ideally the control/comparison group would have fairly horizontal rungs. The treated group would have somewhat consistently slanted rungs.
