Avoiding is easy in theory: you need decide on math methods in advance. Generate random data before you start to gather real data, and write an R program to process this data. Test it, debug, and when you get real data just feed it to this program. Without changing the program. It is harder in practice though. > understanding correlation vs causation > I'd love more information on best practices especially for experimental design I learnt it with experimental psychology. С. James Goodwin "Research in Psychology"[1], there are some specific psychological topics covered (you might not be interested in ethics of psychological research), there are not a word about chi squares or other math methods you mentioned (data processing is out of the scope of the book), but there are a lot about different experimental setups, with a lot of examples. IIRC there is discussion of p-hacking too. I believe this book is a good read to anyone interested in design of experimental and/or correlational research methods in general, not just for psychologists.
