Every time you do another hypothesis test there's a higher probability that some test result you've reported is wrong. His suggested work-around for this was to grab passers-by and have them do the analysis instead.<br /><br />I think it was at about this time that I decided to renounce hypothesis testing, throw my lot in with the Dark Side, and come out as a Bayesian.Michael Bedwardhttps://www.blogger.com/profile/17736007204837985875noreply@blogger.comtag:blogger.com,1999:blog-8503889855562099029.post-69973490835121522692010-02-24T13:59:01.564-05:002010-02-24T13:59:01.564-05:00Todd -- I think some people in the other sciences ...Todd -- I think some people in the other sciences would say those of us in the statistical sciences are even less sure than they. There's this running joke -- if you need statistics to interpret your data, you're not doing science. Hehe. And then there's that PhD comic where the student says "I did a K-S test on my data" and the professor goes "Oh, that bad huh?"<br /><br />Ah, statistics :-)Livia Blackburnehttps://www.blogger.com/profile/15805379309049803903noreply@blogger.comtag:blogger.com,1999:blog-8503889855562099029.post-62299814853601119242010-02-24T12:59:32.000-05:002010-02-24T12:59:32.000-05:00Oh, I think scientists are the most skeptical peop...Oh, I think scientists are the most skeptical people in the world, both by nature and by profession. If you ask a good scientist whether he's *sure* the sun will rise tomorrow morning, he'll tell you that it's impossible to be *sure* about anything.<br /><br />If you flip a coin 100 times and it's heads every time, it's still possible that it's a fair coin, and that has to be acknowledged.<br /><br />At some point, though, when you want to actually apply science to real-life, you have to set a threshold for "Even though I'll never be sure, this is close enough." So even though we're not *sure* of the laws of physics, we can put a man on the moon. And even though we're not *sure* of how bacteria reproduce and spread, we can make some pretty good antibiotics.<br /><br />Speaking scientifically, I'm not *sure* that evolution through natural selection explains the origins of our species, or that there is an anthropogenic effect on the climate, or that the sun will rise tomorrow. But if I were a betting man, I'd bet all the money I have on any of those.<br /><br />Toddtoddtnoreply@blogger.comtag:blogger.com,1999:blog-8503889855562099029.post-48317576998852020382010-02-24T09:55:51.049-05:002010-02-24T09:55:51.049-05:00So glad to hear a scientist admit that everything ...So glad to hear a scientist admit that everything is tentative - what's the deal with those global warming scientists? <br />Anyway, Livia I think I saw your name on Elana Johnson's post as one of the winners of her contest.
