Many of us learn biostatistics in school. We learn lots of equations, and how to use different software, like SPSS, STATA, etc… And some even learn lots of python programming to do complex statistics, but many of us don’t have the foundation of what tests to use when…

I have done a quick Google search and found these charts quite useful for student learning. If you are at the point where you don’t really know what kinds of tests to use for your data, look at these charts. While these charts are not exhaustive in terms of the types of tests to use, I have chosen them because they are simple to understand. Use these charts as a basis and then Google or ask your favourite Gen AI chatbot for more information on how to conduct these tests in your statistical program/software.

Disclaimer: I do not guarantee the accuracy or reliability of these tests. Users are encouraged to find out more about these tests to identify if the tests are appropriate for their data and analyses.

I have included these images, but the credit goes to the orginal sources. I have listed them here for convenience, and in no particular order. Use the one that you find it the easiest to understand and follow.
