16 To validate the analysis, the assumption of bivariate normality should be verified. However, with only eight points, all but severe violations of normality are likely to go undetected. In addition, marginal normality does not guarantee the bivariate normality needed for the techniques above. Methods for assessing bivariate normality directly suffer from the same lack of power problematic in the univariate case. Although the basic conclusions of the analysis are not in doubt, the dataset could be used as motivation for multivariate nonparametric techniques in an advanced course.
