About score calculation

by stmk407 » Sun Nov 30, 2008 1:22 pm
Hi Eric,
Thank you for such a great site! You have much experience with lots of people so is suppose you know some information about score calculation. I really can't understand the same people getting 750 with one q48 v 46,the other q48 v44 or with q50 v41 one 750 the other 760. How can this happen, , think this is very unfair.
Or anyone who has knowledge can help me understand.

If I understand your question correctly, you're asking how you can get a different raw score but the same overall score, or get the same raw scores but different overall scores.

First answer: The difference between a 44 and 46 on verbal is tiny; I believe both of those scores are still in the 99th percentile (or at least very close to it). Since they are essentially the same score, it doesn't really affect the 200-800 overall score.

Second answer: The percentiles change over time, so it's possible that what used to be a 760 is now "only" a 750. I know that 750 used to be 99th percentile, but now it's 98th, for example.

Hope this clears things up!

Thanks for answering but i still cant understand the second one. I thought the same thing but the difference between the dates are only 2 weeks! I still think it is unfair because with 2 weeks difference the same raw scores get differet 200-800 scores.
