The Logic of the Statistical Hypothesis Test

American Journal of EEG Technology, 1994
ABSTRACT.This paper explains in simple language the logic of the statistical hypothesis test. Described are such concepts as sample and population, Type I and Type II errors (false positives and false negatives), power, level of confidence, and one- and two-tailed tests. A Glossary with definitions is provided at the end.

Introduction to Inferential Statistics and Hypothesis Testing

Journal of the American Academy of Child & Adolescent Psychiatry, 2000
When performing research, rarely are we able to work with an entire population of individuals. Instead, we usually test our treatment or intervention on a sample of individuals from the population. It is hoped that, if our treatment is successful, we can infer that the results from our sample apply to the population of interest.

Understanding statistical hypothesis tests and power

Medical Journal of Australia, 2017
Medical researchers often attempt to understand whether a risk factor is involved in the aetiology of disease or whether an intervention reduces disease; this has been the subject of another article in this series.1 We typically do this by proposing scientific hypotheses from which testable statistical hypotheses can be developed.

A New Statistic for Bayesian Hypothesis Testing

Econometrics and Statistics, 2023
Abstract A new Bayesian–inspired statistic for hypothesis testing is proposed which compares two posterior distributions; the observed posterior and the expected posterior under the null model. The Kullback–Leibler divergence between the two posterior distributions yields a test statistic which can be interpreted as a penalized log–Bayes factor with ...

Hypothesis Testing and Statistics

2016
Every quantity that is estimated from the data, such as the mean or the variance of a Gaussian variable, is subject to statistical fluctuations of the measurements. For this reason they are referred to as a statistics. If a different sample of measurements is collected, statistical fluctuations will certainly give rise to a different set of ...

Alternatives to statistical hypothesis testing in ecology: a guide to self teaching.

Ecological Applications, 2006
Statistical methods emphasizing formal hypothesis testing have dominated the analyses used by ecologists to gain insight from data. Here, we review alternatives to hypothesis testing including techniques for parameter estimation and model selection using

Statistical hypothesis testing in biology: a contradiction in terms.

Journal of Economic Entomology, 1986
We respond to the preceding article by Perry (J. Econ. Entomol. 79: 1149–1155) concerning the subject of hypothesis testing and meaningful presentation of statistical analyses. We agree with Perry that indiscriminate use of statistical hypothesis testing

Hypothesis Statement and Statistical Testing: A Tutorial

BOHR International Journal of Operations Management Research and Practices, 2022
Many researchers and beginners in social research have several dilemmas and confusion in their mind about hypothesis statement and statistical testing of hypotheses. A distinction between the research hypothesis and statistical hypotheses, and understanding the limitations of the historically used null hypothesis statistical testing, is useful in ...
