Online help for choosing the correct statistical test or model
Recently there have been several digital tools to help researchers select the most appropriate statistical test. I have not tested any of these but they look promising.
- StatXFinder is a web-based tool. It is discussed inthe publication Suner et al 2015. StatXFinder: a web-based self-directed tool that provides appropriate statistical test selection for biomedical researchers in their scientific studies.
- SOFA: Statistics Open For All is a desktop program the works on multiple platforms. There’s a brief overview on Wikipedia. It is also discussed in the publication Johnson and Karunakaran 2014. How to Choose the Appropriate Statistical Test Using the Free Program “Statistics Open For All” (SOFA)
- The BioStat Decision Tool works on Android and Apple handheld devices. It is discussed in PeerJ Preprint: Wiles and Bisho 2013. Common mistakes in data presentation and statistical analysis: how can the BioStat Decision Tool help?
- See below for my version of descision tree for different types of basic statistical analyses.
- GUSTA ME: The GUide to STatistical Analysis in Microbial Ecology in a web-page tool that offers to help sort through the alphabet soup of multivariate stats (PCA, PCoA, DA, FA, NMDS…). It is detailed in the paper: Buttigieg & Ramette (2014) A Guide to Statistical Analysis in Microbial Ecology: a community-focused, living review of multivariate data analyses. FEMS Microbiol Ecol. 90: 543–550.
