To assure that a hypothesis is tested as rigorously as possible, the proper statistical method must be used to analyze the data. But without a strong background in statistics, it may be difficult to determine the efficacy of the data analytic technique used in the study. This paper describes several widely used data analytic techniques and offers examples of their proper application in orthopaedic research design.
为确保对假设进行尽可能严格的检验，必须使用恰当的统计方法来分析数据。但如果没有扎实的统计学背景，可能很难确定研究中所使用的数据分析技术的有效性。本文介绍了几种广泛使用的数据分析技术，并提供了它们在骨科研究设计中正确应用的示例。
