| − | In this comic, Megan and Cueball come to see some scientists to investigate their theory that jelly beans cause acne. The scientists of course do not want to stop playing the addictive game {{w|Minecraft}} (which has been referenced in a [[861|previous xkcd]]).
| + | ==Transcript== |
| − | | + | :[ {{w|Sauron}} is in a nightclub, sitting unhappily at a table with a drink. The Beyoncé song "{{w|Single Ladies (Put a Ring on It)|Single Ladies}}" is playing. Beret Guy walks up to Sauron.] |
| − | When the scientists come back and say there is no link between jelly beans and acne, Megan and Cueball have heard that it is specific colors that cause acne. So, the scientists tear themselves away from Minecraft again and study each and every color (including mauve and turquoise - I didn't know those were real colors for jelly beans). Green is the only color that has any link. So, obviously the news blows the coverage out of control, even though as we see in the image text that the green jelly beans study may have been a coincidence.
| + | :Beret Guy: Hey Sauron. Why so Glum? |
| − | | + | :Saron: Gil-Galad saw through me and threw me out of Lindon. Galadriel, too. I'll never rule anyone at this rate. |
| − | But, of course, the news coverage in all caps in the image text blows it out of proportion again.
| + | :[Single Ladies continues playing] |
| − | | + | :Sauron: Eru created such beautiful creatures - Elves and Men and Dwarves - and all I've got are these stupid Orcs. |
| − | More to the point, the scientists studied 20 different colors, and only one showed a link at the 95% confidence level. The 95% confidence level MEANS that there is a 95% chance that the link is not random. So by definition we would expect 1 out of 20 studies to show a link at this level by pure random chance.
| + | :[Music: 'cause if you liked it, then you should have put a ring on it] |
| − | This is a big problem in correlation research generally, because scientists study many different possible causal factors, and then report the ones that show significance. Without a plausable causation mechanism it’s not clear what value such studies have, given that 1/20 will randomly show a correlation at (p>.05). For more: http://www.fallacyfiles.org/multcomp.html
