Impact of sample and its statistical properties on the appropriate choice of statistical methods in medical research

This article details the source of sample randomness， sample acquisition methods， independent identically distributed samples， statistics， sampling distribution and so on， in order to explore which conditions should be met for the application of statistical methods and why these conditions should be met， so as to improve the scientific nature of medical papers.
