Subject   st: on-line interactive statistics tutorials for absolute beginners

I am setting out to design an elective for fourth year medical students in "information mastery," critical appraisal of research literature, and statistical reasoning. This will be for people destined to be more "consumers" of the literature, rather than producers. And medical students are not known for their interest in things mathematical. So the emphasis will not be on doing calculations or running statistical tests. I will talk mostly about non-statistical issues of study design, but I will want to touch upon some statistical concepts, in very general terms:

1. what tests are useful for what types of data and research questions,
2. concepts of populations, samples, sampling distributions,
3. the logic behind classical statistical inference,
4. concepts of central tendency and dispersion
5. distinction between P-value and effect size (statistical significance in contrast to clinical meaningfulness)
6. some of the common dangers in interpreting statistics in studies (multiple comparisons, joint outcome variables (like dead-or-disabled), and stepwise regression.

Does anyone have any suggestions for good on-line interactive tutorials on any of these topics?

Thanks.
