Alpha risk is the risk in a statistical test of rejecting a null hypothesis when it is actually true.

Hypothesis testing involves discerning the effect of one factor on another by exploring the relationship's statistical significance. Hypothesis testing in business examples might include a ...

Multivariate analysis of variance (MANOVA) is an extension of the commonly used analysis of variance (ANOVA) method, allowing statistical comparisons across three or more groups of data and involving ...

This paper presents and illustrates a simple statistical test for judging whether one of two materials or treatments is better than the other. The data to which the test is applied consist of paired ...

A new method, R-scape, tests whether observed sequence covariation supports a conserved secondary structure in RNA. The program finds no evidence for previously proposed conserved secondary ...

In this paper, an asymptotically valid statistical test is derived for PBE under the 2 × 2, 2 × 3 or 2 × 4 crossover design, using the method of moments and linearization. A method of determining the ...

Testing the hypothesis The main tool of the fourth stage is hypothesis testing, a formal statistical procedure during which the researcher makes a specific statement about the true value of an ...
