Who is the Panel Data poster for?

Panel Data belongs to the Economics section rather than to a school year, because business is not something one grade owns. Anyone learning econometrics can pin it up — a beginner, a student mid-course, or someone revising years later.

Observing each unit repeatedly lets you remove everything fixed about it. A wall chart earns its place by being glanceable from where the work is happening, so Panel Data belongs on the wall where that business work actually happens, within glancing distance, rather than filed away.

What other posters go with Panel Data?

What size does the Panel Data poster print at?
