As someone who needs statistical knowledge but is not a formally trained statistician, I'd find it helpful to have a flowchart (or some kind of decision tree) to help me choose the correct approach to solve a particular problem (eg. "do you need this and know that and that and consider data to be normally distributed? Use technique X. If data is not normal, use Y or Z").

After some googling, I've seen several attempts of various coverage and quality (some not available at the moment). I've also seen similar flowcharts in statistics textbooks I've consulted in libraries.

A bonus would be an interactive site that, besides just having a chart, would provide extra info (such as assumptions) and would point to how to perform those techniques in popular stat packages. "Need to do ANOVA in R? You need package X and here's a tutorial".

I'm asking as a community wiki question in the hope there are better resources I couldn't find. Since statistics is a large subject, I think such a flowchart would be suitable for techniques that can be approached by someone who has beginner or intermediate-level knowledge. Anything more complicated would need someone with formal training.

These are not really interactive flowcharts, but maybe this could be useful: (1) http://j.mp/cmakYq, (2) http://j.mp/aaxUsz, and (3) http://j.mp/bDMyAR.

You can look at the solution given on the question "Statistical models cheat sheet"

I know this is bit old now but we have just made this (corrected see below) http://piiq.co.uk/Stats, and interactive stats test flowchart. Let me know what you think. (This is based on an Andy Field flowchart from a text-book, linked on the site).

EDIT: New URL is http://www.statsflowchart.co.uk

  • $\begingroup$ Might be worth mentioning in your answer that this is based on the flowchart put together by Field (presumably in one of his statistics for psychology books?) $\endgroup$ – Silverfish Aug 26 '16 at 12:20

  • $\begingroup$ Hi, Thanks for highlighting. It has now moved to a dedicated URL: statsflowchart.co.uk $\endgroup$ – Matt Jackson May 31 '18 at 10:52
