What’s on the Sampling People poster
A 6-row table: Strategy · How drawn · Best for.
Probability supports inference. Non-probability supports description.
- Simple random — Equal chance from a list — Clean inference
- Stratified — Random within known groups — Small subgroups
- Cluster — Whole units, then within — Dispersed populations
- Quota — Fill set counts, not random — Speed, no frame
- Snowball — Referral from participants — Hidden populations
- Theoretical — Chosen to test an idea — Grounded theory
The sampling frame is the usual weak point: who is missing from the list is invisible in every result drawn from it.

- Who is the Sampling People poster for?
- Sampling People belongs to the Sociology 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 Sampling People poster?
- When deciding who to study and what your findings will then cover. A wall chart earns its place by being glanceable from where the work is happening, so Sampling People belongs on the wall where that law & society work actually happens, within glancing distance, rather than filed away.
- What other posters go with Sampling People?
- Claiming a Cause, Coding Qualitative Data and Ethnography sit alongside Sampling People in the Sociology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Claiming a CauseCoding Qualitative DataEthnography
- Is the Sampling People poster free to download and print?
- Yes. Sampling People downloads as a free PDF with no account, no email and no watermark, like everything else in the Sociology 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 Sampling People poster print at?
- Sampling People 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 Sampling People loses nothing.Printing guide
