In general, better understanding of the need and usage of statistics would benefit the medical community in India. This paper explains why statistical analysis is needed, and what is the conceptual basis for it. Ophthalmic data are used as examples. The concept of sampling variation is explained to further corroborate the need for statistical analysis in medical research. Statistical estimation and testing of hypothesis which form the major components of statistical inference are construed. Commonly reported univariate and multivariate statistical tests are explained in order to equip the ophthalmologist with basic knowledge of statistics for better understanding of research data. It is felt that this understanding would facilitate well designed investigations ultimately leading to higher quality practice of ophthalmology in our country.
总体而言，更好地理解统计学的需求和用途将使印度的医学界受益。本文解释了为何需要进行统计分析以及其概念基础是什么。以眼科数据为例进行说明。解释了抽样变异的概念，以进一步证实医学研究中进行统计分析的必要性。阐述了构成统计推断主要部分的统计估计和假设检验。解释了常见的单变量和多变量统计检验，以使眼科医生具备统计学基础知识，从而更好地理解研究数据。人们认为，这种理解将有助于精心设计的调查，最终提高我国眼科的医疗质量。
