Star Trek Analytics.

Matt Bailey uses Star Trek to teach analytics. In this example, he tackles the “red shirt” phenomenon. Part of his data:

* Yellow-shirt crewperson deaths: 6 (10%)
* Blue-Shirt crewperson deaths: 5 (8 %)
* Engineering smock crewperson deaths: 4
* Red-Shirt crewperson deaths: 43 (73%)

So, the basic segmentation of factors allows us to confirm that red-shirted crewmembers died more than any other crewmembers on the original Star Trek series.

He then goes into an in-depth analysis, with the conclusion that red shirts are more likely to survive when Captain Kirk finds a love interest. Link -via Metafilter
