Sample size and power: What Is enough? 来自 Semantic Scholar 喜欢 0 阅读量: 46 作者: C Phillips 摘要: A basic understanding of statistical methodology is essential, both for designing quality research projects and for evaluating the medical literature. This article deals with the basic principles...
The central limit theorem makes it appropriate to use the z-test with an unknown variance if the sample size is large enough (n ≥ 30), regardless of the distribution of the population. Since the t- and the z-distributions converge as sample size increases, either test is appropriate, alth...
2. Sample Size No matter what data analysis methods are used for quantitative research, the sample size is kept small enough to represent the target market. Source The main aim of the research methodology is to obtain numerical insights, so the sample size should be fairly large. Depending on...
shortcoming only arises when there’s a need for perfect normality. The t-distribution should only be used when the population standard deviation is not known. If the population standard deviation is known and the sample size is large enough, the normal distribution should be used for better ...
