精确样本量的计算是研究设计的重要组成部分。重要的是要了解，不同的研究设计需要不同的样本量计算方法，不能在所有设计中使用一个公式。在这篇简短的综述中，我们试图教育研究人员关于不同研究设计可用的各种样本量计算方法。在这篇综述中，提到了最常用的研究设计的样本量计算。对于遗传和微生物学研究，读者被要求阅读其他来源。
Calculation of exact sample size is an important part of research design. It is very important to understand that different study design need different method of sample size calculation and one formula cannot be used in all designs. In this short review we tried to educate researcher regarding various method of sample size calculation available for different study designs. In this review sample size calculation for most frequently used study designs are mentioned. For genetic and microbiological studies readers are requested to read other sources.
