    ABSTRACT

    Aim: To improve the medical researchers' discriminative analysis of misu sed common statistics and the correct utilization ratio of statistics. M ethods: To expound clearly the similarities and differences and the appl icability of various common design types in medical experiments, and to reveal t he cause and harm of these common errors in statistical application. Res ults: To present the sufficient reasons for irreplacability of the analy sis of variance by t-test and main points concerning correct application of st atistics. Conclusion: Improvement of their utilization of statistics requires that medical researchers should receive constant training in statistic s and guidance in order to cooperate with statisticians in the scientific and re search work. ......
