"Hack your way to Scientific Glory"

This interactive website is really slick: it's a demonstration of inferential statisitcs - p values - and how "statistical significance" is influenced by factors like samplke size and number of variables included in the calculation.

Note: the content of the website (political party power and economic indicators) might be distracting to some students in some contexts?

The interactive feature is halfway down the page. The text at the top and bottom of the page is interesting too: a good discussion of how we need to be very critical and careful consumers of statistical findings (since data can be "hacked" to produce significance). (Note: some profanity in the text).
