Hypothesis Testing with Finite Statistics

open access: yesThe Annals of Mathematical Statistics, 1969
Let $X_1, X_2, \cdots$ be a sequence of independent identically distributed random variables drawn according to a probability measure $\mathscr{P}$. The two-hypothesis testing problem $H_0: \mathscr{P} = \mathscr{P}_0 \operatorname{vs.} H_1: \mathscr{P} = \mathscr{P}_1$ is investigated under the constraint that the data must be summarized after each ...

Addressing common inferential mistakes when failing to reject the null-hypothesis [version 3; peer review: 2 approved]

open access: yesF1000Research
Failure to reject a null-hypothesis may lead to erroneous conclusions regarding the absence of an association or inadequate statistical power. Because an estimate (and its variance) can never be exactly zero, traditional statistical tests cannot ...

Statistical significance and statistical power in hypothesis testing [PDF]

open access: yesJournal of Orthopaedic Research, 1990
AbstractExperimental design requires estimation of the sample size required to produce a meaningful conclusion. Often, experimental results are performed with sample sizes which are inappropriate to adequately support the conclusions made. In this paper, two factors which are involved in sample size estimation are detailed—namely type I (α) and type II

A Pragmatic Approach to Statistical Testing and Estimation (PASTE)

open access: yesHealth Professions Education, 2018
The p-value has dominated research in education and related fields and a statistically non-significant p-value is quite commonly interpreted as ‘confirming’ the null hypothesis (H0) of ‘equivalence’.
