When hypothesis testing is performed during packaging validation, software can be used to specify the acceptable defect level, the detectable difference, and the corresponding probability of the ...

This paper introduces the normal probability plot correlation coefficient as a test statistic in complete samples for the composite hypothesis of normality. The proposed test statistic is conceptually ...

Unfortunately significance testing and hypothesis testing are of limited scientific value – they often ask the wrong question and almost always give the wrong answer.

The Simes method for testing intersection of more than two hypotheses is known to control the probability of type I error only when the underlying test statistics are independent.

Parametric tests make assumptions that aspects of the data follow some sort of theoretical probability distribution. Non-parametric tests or distribution free methods do not, and are used when the ...

Most SEO teams still rely on checklists and guesswork. Learn how a hypothesis-driven approach leads to faster and smarter results.
