Who is the Selecting Cases poster for?
Selecting Cases belongs to the Political Science section rather than to a school year, because law & society is not something one grade owns. Anyone learning research methods can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Selecting Cases poster?
Choosing cases by their outcome guarantees you will find the pattern you expected. A wall chart earns its place by being glanceable from where the work is happening, so Selecting Cases belongs on the wall where that law & society work actually happens, within glancing distance, rather than filed away.
What other posters go with Selecting Cases?
Reading a Study Critically, Asking a Researchable Question and Case Studies sit alongside Selecting Cases in the Political Science section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Reading a Study CriticallyAsking a Researchable QuestionCase Studies
Is the Selecting Cases poster free to download and print?
Yes. Selecting Cases downloads as a free PDF with no account, no email and no watermark, like everything else in the Political Science section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Selecting Cases poster print at?
Selecting Cases is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Selecting Cases loses nothing.Printing guide
