ANOVA on ranks means that a standard analysis of variance is calculated on the rank-transformed data. Conducting factorial ANOVA on the ranks of original scores has also been suggested. However, Monte Carlo studies, and subsequent asymptotic studies found that the rank transformation is inappropriate for … Skatīt vairāk In statistics, one purpose for the analysis of variance (ANOVA) is to analyze differences in means between groups. The test statistic, F, assumes independence of observations, homogeneous variances, and population Skatīt vairāk Ranking is one of many procedures used to transform data that do not meet the assumptions of normality.
