I submitted my first paper to a peer-reviewed journal and got lots of feedback, questions and criticism back. One point was related to the number of digits I report for estimated values (e.g. for Cronbach's alpha values or for regression coefficients). The reviewer asks me whether it is justified that I use e.g. four digits for my Cronbach's alpha estimates. Actually, I just took the output from Stata and thought that if Stata reports these estimates, I can report them as well. I guess the question implies that is not realistic (and not necessary) to report four digits. How do I know how many digits are okay?
Thanks a lot!
