摘要: This is an account of what I have learned (so far) about the application statistics to psychology and other sociobiomedical sciences. It includes principles "less more" (fewer variables, more highly targeted issues, sharp rounding off), "simple better" (graphic representation, unit weighting for linear composites), "some things you learn aren't so." avoid many misconceptions that surround Fisherian null hypothesis testing. also importance power analysis determination just how big (rather than statistically significant) are effects we study. Finally, there no royal road statistical induction, informed judgment investigator crucial element in interpretation data, take time.
