Hypothesis brings clarity, specificity and focus to a research problem. There are two types of hypothesis which are called the Null Hypothesis and the Alternative Hypothesis. There are four steps in hypothesis testing. After getting the results, the researcher tests whether...

留学生统计学系列—chap.6假设检验(Hypothesis Testing) 假设检验(Hypothesis Testing)是一种统计方法,用于评估关于总体参数的陈述或假设是否成立。它通常用于分析实验数据,调查统计样本,或研究总体特征。在假设检验中,通常有两个互相排斥的假设,它们分别被称为零假设(H0)和备择假设(Ha): 1. 零假设(H0) 这是一个...

Null Hypothesis Significance Testing(NHST)可谓是神经科学、心理学和生物医学领域研究中最为常见且常用的传统统计技术,也是近年来爆发的重复性危机中被广泛讨论的标的之一。很多人对NHST等一系列工具的问题有所了解,但实际上仍是非常浅薄。frontiers in Human Neuroscience在17年8月的这篇文章是在我有限的阅读中较为...
the estimates that state research creates can still be thought to be estimates of unknown population parameters. With this conceptualization, hypothesis testing may still seem to be useful. Nevertheless, many argue that confidence intervals or, perhaps, more complex estimation techniques such asBayesian...

In any case, it is the facts that speak to the observer. Not surprisingly, then, one of the most fundamental notions of positivist science is the separation of analytical (often called metaphysical or logical) arguments (not directly observable) from empirical (by definition testable) statements....
According to the textbook standard definition, “A critical value is a cutoff value that defines the boundaries beyond which less than 5% of sample means can be obtained if the null hypothesis is true. Sample means obtained beyond a critical value will result in a decision to reject the null...
