There are hundreds of statistical tests available. Possibly thousands.
And every colleague you ask has a (different) opinion about which one you need in your research.How do you choose which one is the right one?
To figure that out, you first need to answer questions about your research question, your design, your variables, and the data itself.
The answers to these four questions will come together to greatly narrow down the right analysis.
They're not always easy to answer, and there isn't always one right analysis, but taking the time and thought to do so before you collect data will save you hours of time and frustration down the line.
