We all know that sometimes the skaters' scores "seem" right and sometimes they "seem" wrong. One measure I've used to sort it out is figuring out the standard deviation in the scores. Basically, if all judges give identical scores, standard deviation will be 0; when judges seriously disagree, the deviation increases. I wrote a little program to figure out what got what deviations. If there's interest, I can post all of the results I got (a lot of numbers there!), but here are some highlights:
- The biggest agreement among the judges was for the components of Davis and White in all four programs; in the free, especially - the deviation was a mere 0.078. There was also remarkable agreement on Volosozhar and Trankov.
- Judges disagreed most on Plushenko's components - deviation of 0.62 in short, 0.88 in free during the team event (though in general, deviations were greater in team then in the individual).
- On the technical side, some if the biggest disagreements among the judges were in ladies' short, with Lipnitskaya's standard deviation being 0.68 and Wagner's 0.64.
- What I found interesting (and in part why I went through this exercise) was to compare Kim and Sotnikova's deviations in the free. This surprised me, as I expected a great deviation, especially on Sotnikova's components. In fact, it was not nearly as big as I thought - on the technical side 0.392 for Kim, 0.586 for Sotnikova; for components, 0.35 for Kim, 0.34 for Sotnikova (for Sotnikova, most agreement among judges on Interpretation, least on Performance).
