An intriguing possibility that I toss out for consideration by Murray and Engel, to which I don't yet know the answer, is whether we could use a ranking of the the most successful female singers and then note the frequency of breast cancer as a function of rank.  If 2 out of the top 20 developed breast cancer at a young age, wouldn't that be alarming?  That approach presents a good intellectual challenge.--[[User:Aschlafly|Aschlafly]] 20:26, 24 May 2008 (EDT)

:As I said, yes, the list of all actresses has far more irrelevant names than relevant ones.  But you're starting with a valid list of half a million - would you imagine even 1% of that list is valid?  That's 5,500 individuals.  And starting with the NYC phone book would be better than starting with a list displaying nothing but [[selection bias]], as you have here, since that would be essentially random, unlike your list.  The key to understanding all statistical analysis is understanding that one's sample MUST be random, as countless others have pointed out above.

:As to your suggestion, a population size of 20 is not an adequate population upon which to test a theory about a medical condition.

:Finally, I want to return to an earlier point made by others.  It seems the vast majority of the women you have listed here have indeed born children.  How does this fit into your theory?  [[User:EngelUmpocker|EngelUmpocker]] 20:45, 24 May 2008 (EDT)
