hypothesis testing

n
(Statistics) statistics the theory, methods, and practice of testing a hypothesis concerning the parameters of a population distribution (the null hypothesis) against another (the alternative hypothesis) which will be accepted only if its probability exceeds a predetermined significance level, generally on the basis of statistics derived from random sampling from the given population. Compare statistical inference

They cover the basics of statistics; the design of experiments; the axioms of statistical inference: estimation and hypothesis testing; the assessment of sampling techniques: theory and application; time series; an overview of statistical software packages: MS Excel, SPSS, Minitab, and R; and an overview of JMP and SAS.
Since statistical significance was not achieved for ORR, the hypothesis testing of OS was not formally performed.
The instructional materials provided in this article have been designed to address these fundamental engineering concepts while being flexible with respect to project length (e.g., one-time, semester long, etc ...), project assessment method (e.g., report, PowerPoint, poster, video, prototype, etc ...), and project concepts (e.g., description statistics, regression, hypothesis testing, etc.), depending on the needs of the students.
In this paper, we propose a novel DLPL scheme, called SDL (Sequential hypothesis testing based Dynamic LPL), which employs sequential hypothesis testing to decide whether to change the polling interval conforming to various traffic conditions.
In this paper, hypothesis testing is adopted to solve the water pollution detection problems.
By contrast, only 3 of the 281 papers (1.1%) considered the effects of multiple hypothesis testing on their scientific conclusions.
Summary: We briefly reviewed and provided cautions about some of the fundamental concepts used in the design of medical and public studies, especially primary question, hypothesis testing and sample size in this short note.
Psychometric research adopting quantitative methods make use of hypothesis testing in order to measure differences between scores (Cohen, 1992).
"I have to teach hypothesis testing, since it is so prevalent in biomedical research, but life would be much easier if we could just focus on estimates with their associated uncertainty.
In inferential statistics, specifically in hypothesis testing, there are two contending hypotheses: the null hypothesis (H0) and the alternative hypothesis (), in which the objective is to gather evidence through sampling that would either support or reject one of the hypotheses.
The Bayes factor is a measure of the evidence from the current study and has a key role in Bayesian hypothesis testing. It is the ratio of the posterior probability for the experimental outcome if the outcome was produced by the alternative model divided by the posterior probability for the experimental outcome if the outcome was produced by the null model.
In Table 1, which is named under the title of hypothesis testing, inferential statistics such as the Pearson correlation coefficient (R) is used.
