At first this did not handle variables in the current dataset: it was purely and simply for processing pre-given sample statistics (you entered two means, or whatever). Now that the "calculator" _can_ handle variables in the current dataset, it has arguably rendered the "Bivariate tests" menu item redundant. Any thoughts on whether we should scrap the latter? Any votes for keeping it? Allin.
