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.
精确样本量的计算是研究设计的重要组成部分。必须明白，不同的研究设计需要不同的样本量计算方法，不能在所有设计中都使用同一个公式，这一点非常重要。在这篇简短的综述中，我们试图让研究人员了解适用于不同研究设计的各种样本量计算方法。在这篇综述中提到了最常用研究设计的样本量计算方法。对于基因和微生物学研究，建议读者阅读其他资料来源。
