Ethical conduct is an essential component in research, especially in medica
l research. Statistical methods for design and analysis are powerful resear
ch tools if used properly. Abuse of these principles and methods are just a
s unethical as other laboratory or clinical misconduct, Inadequate research
design can produce worthless results and thus wastes effort and valuable r
esources. For clinical research, patient resources ale wasted. Inappropriat
e analysis of data can also produce misleading results and conclusions. For
clinical research, inferior therapy might be given to patients as a conseq
uence. These ethical concerns can have implications for and affect the indi
viduals responsible for the statistical design and analysis. Examples are p
rovided which illustrate some possible abuses and inappropriate pressures.
