I didn’t watch it, but jeez Ryan, if you were having trouble with it, could have just asked. Every time I have explained that to someone, I usually just proved with with like, a hypothetical 9,000 trials or something. :o
(Yay College!)
Heheheh, I remember rolling dice to prove the Monty Hall thing to my middle-school classmates who wouldn’t believe me. They still didn’t really want to believe me, but they couldn’t argue with the numbers once I got up to 20 trials using each algorithm (switch, don’t switch) or so.
RE:Smoking
Interesting. After just reading this article about how smoking is mostly negligible during the first 5 months of pregnancy, I kind of wish they used a larger test set (150 vs 6860 in the smoking-is-negligible study) and examined issues like “First 5 months” vs “Last 4 months”. Might provide some more granular insight into the whole thing.
If you want a wonderful example of sexism in the higher maths and sciences, I’ll loan you Marilyn vos Savant’s collection of letters in response to the (correct) answer to the problem she posted in her weekly column. Whoever knew that under the lab coats, so many male professors had their panties in a great Gordian knot?
@Clint: I linked to that article also recently. I agree with you about the need to use larger data sets. It was a small data set that led to the “abortions cause breast cancer” nonsense a few years back.
@flyingsirkus: Sounds interesting. I just wikied the story. I didn’t realize there was sexism involved, but can see how that could happen. Many scientists believe sexism is behind the hostile rejection of the Aquatic Ape hypothesis also.
