BACKGROUND AND OBJECTIVE
The inadequate use of basic statistics is the main responsible for scientific article misinterpretation. The purpose of this review article was to review some basic statistical topics to alert authors and readers about the importance of basic statistics proper reporting.
CONTENT
A bibliographical and cross-sectional study was carried out,which analyzed publications in books and articles in the following databases: SciELO (Scientific Electronic Library Online) and PubMed (Available from the National Center for Biotechnology Information). Medical research is not free from the risk of false positive and false negative results due to the choice of statistical tests and presence of small sample sizes.
CONCLUSION
Understanding the correct use of basic statistics leads to fewer errors in reporting the results of studies performed and in the interpretation of their conclusions.
背景与目的
基础统计学运用不足是导致科学文章被误读的主要原因。这篇综述文章的目的是回顾一些基础统计学主题，以提醒作者和读者正确报告基础统计学的重要性。
内容
开展了一项文献学和横断面研究，分析了以下数据库中书籍和文章的出版物：SciELO（科学电子图书馆在线）和PubMed（可从国家生物技术信息中心获取）。由于统计检验的选择和小样本量的存在，医学研究难免会出现假阳性和假阴性结果的风险。
结论
理解基础统计学的正确使用方法，可减少研究结果报告及其结论解读中的错误。
