- Who is the Choosing a Test poster for?

- When should you use the Choosing a Test poster?
- Three questions: what are you testing, what design, and what level of measurement. A wall chart earns its place by being glanceable from where the work is happening, so Choosing a Test belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Choosing a Test?

- Yes. Choosing a Test downloads as a free PDF with no account, no email and no watermark, like everything else in the Psychology 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 Choosing a Test poster print at?
- Choosing a Test 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 Choosing a Test loses nothing.Printing guide
