Hi The levels of measurement requirement for parametric stats is one with which I (and others) disagree, which is why I just discriminate between categorical and numerical variables in my decision tree, and why I tend not to teach much about nonparametric statistics (although I make references to them). Here is one brief summary of the debate, coming down on my side in the end of course!
http://www.sagepub.com/upm-data/19708_6.pdf I haven't followed it as much, but is it not also the case that many inferential tests match very closely with the results from randomization tests ... further legitimizing the validity of the inferential statistics?

Others format it somewhat differently. Probably the biggest question would be "where do you stop?" Would you include multivariate statistics and things like Structural Equation Modeling? My decision tree is limited to the basics of Intro Stats (and it doesn't include single-sample stats for comparing a sample mean to a population mean like the single sample z or t tests although they could easily be added). Mine include (in parentheses) non-parametric options for when the assumptions of a parametric test are not met (such as normality, equal variances or the data is not at the interval or ratio level of measurement). For the purpose of my decision tree, continuous variables are interval or ratio and categorical are nominal. If ordinal data is used, the nonparametric alternatives in parentheses would be appropriate.
