ScoreBeyond predicted New SAT scores using Glicko ratings
- gok2 10y agoReally impressive numbers
- ianceicys 10y agoLooking to take the GMAT, any chance you guys will have GMAT predictive scoring?
- emrekzd 10y agoVery cool. I'm wondering how you guys apply Glicko to this domain when all questions test different subjects.
- bkucukguzel 10y agoThe short answer is we simulate a game for each subject area skill tested by the question. There is a more technical explanation we added to the last part of the blog post.
- emrecan 10y agoIsn't this the good old chess-ranking algorithm used to find the right opponent in halo as well?
- remzisenel 10y agoThis is quite impressive. Rating both the student and the question is brilliant.
- doug1001 10y agoBrilliant. If i understand it correctly, the crucial insight is modeling a test taker's answer to a question as an adversarial game between the question and the test taker (eg, correct answer, the test taker wins). In the test-preparation business, the significance of this must be huge--a student doesn't have to sit down and take an entire 'simulated' test to have a good sense of what their actual score would be; instead a relatively small number of carefully chosen questions will give an accurate prediction. Aside from score prediction, this methodology gives you immediate insight into which subjects a student should spend their prep time and at what level. for those of with children not too far from college age, i hope this is reasonably priced.
