This is the sixth in a series of Tutorials in Clinical Research. The objectives of this tutorial are to produce a brief, step-by-step, user-friendly atlas with clinical scenarios and illustrative examples to serve as ready references and, it is hoped, to open an inviting door to understanding statistics.
Tutorial.
The authors met weekly for 6 months discussing clinical research articles and the applied statistics. Liberal use of reference texts and discussion focused on constructing a tutorial that is factual as well as easy to read and understand.
The tutorial is organized into five sections: Overview, Key to Descriptive Summaries, Steps in Summarizing Descriptive Data, Understanding the Summaries of Specific Data Types, and Understanding Scope or Dispersion of Data.
Assessing the validity of medical studies requires a working knowledge of statistics; however, obtaining this knowledge need not be beyond the ability of the busy surgeon. Desire is the only limiting factor. We have tried to construct an accurate, basic, easy-to-read-and-apply introduction to the task of summarizing the characteristics of a single variable. This is known as descriptive statistics.
这是临床研究系列教程中的第六篇。本教程的目标是制作一本简短、循序渐进、便于用户使用的图谱，包含临床案例和示例，作为随时可用的参考资料，并且希望能打开一扇引人入胜的理解统计学的大门。
教程。
作者们连续6个月每周会面，讨论临床研究文章和应用统计学。大量参考文献并聚焦于构建一个既基于事实又易于阅读和理解的教程。
本教程分为五个部分：概述、描述性总结的关键、总结描述性数据的步骤、理解特定数据类型的总结以及理解数据的范围或离散度。
评估医学研究的有效性需要具备统计学实用知识；然而，获取这一知识并非忙碌的外科医生力所不能及。唯一的限制因素是意愿。我们试图构建一个准确、基础、易于阅读和应用的介绍，以阐述总结单个变量特征的任务。这就是所谓的描述性统计学。
