Abstract. This paper studies the effect of deviating from the normal distribution assumption when considering the power of two many-sample location test procedures: ANOVA (parametric) and Kruskal-Wallis (non-parametric). Power functions for these tests under various conditions are produced using simulation, where the simulated data are produced using MacGillivray and Cannon’s [10] recently sugg...

Methods: Thirty Wistar rats were divided into three groups of 10 animals each: GI, GII and GIII and the mice were euthanized at 7, 14 and 21 days, respectively. Experimental subjects were compared to their respective controls by the Mann-Whitney test. Comparison of values between compression and tension sides were performed during the same and different time periods through Analysis of Variance...

Methods 31 HIV seropositive antiretroviral therapy naïve and 8 HIV uninfected healthy control subjects were recruited and characterized as being early, late or slow progressor. Peripheral blood mononuclear cells were isolated from each study subject and stimulated with HIV-1 subtype ‘C’ gag peptide pool and assessed for IL-17 cytokine producing CD4-T cells using intracellular cytokine staining....

Methods Forty-three JSLE patients (revised ACR criteria, mean age = 14.3 yrs, 36F:7M), and 35 age and gender matched healthy controls were studied; 30 JSLE had SLEDAI score 4, reflected active disease. Soluble molecules were measured by commercial ELISA kits. Lymphocytes and monocytes were stained with specific moAbs and analyzed by flow cytometry. Kruskal-Wallis test and Spearman’s rank were e...
