PPT-Digression - Hypotheses

Many research designs involve statistical tests involve accepting or rejecting a hypothesis Null statistical hypotheses assume no relationship between two or more variables Statistics are used to test null hypotheses. This limitation does not allow us under the procedures of hypothesis testing to address the basic question Does the length the reaction rate the fraction displaying a particular behavior or having a particular opinion the temperature the kinetic ene Virginibus Puerisque: Function of the Human Foreskin Considered from an Evolutionary Perspective COX Microscope Unit, University of Sydney, Sydney, NSW 2006, Australia (Tel: (+61) 2 351 3176; Fax: (+ Prodipto. .

In confirmatory clinical trials of candidate drug and vaccine products the interest is in controlling the family-wise error rate (FWER) at a specified level α. Gaining popularity in many other discovery settings is an interest in maintaining the false discovery rate (FDR) as an attractive alternative to strict FWER control. Yosef Hochberg made impactful contributions to both FWER methods (Hochberg, 1988) and FDR methods (. Yunchao. Wei, Wei Xia, . Junshi. Huang, . Bingbing. Ni, Jian Dong, Yao Zhao, Senior Member, IEEE .
