Hey! I’m considering doing some LSAT tutoring, but this data from LSAC has been bugging me for a while.
I’m a total statistical layman, but it seems, on its face, to suggest that studying for the LSAT, by any method, has (basically) no effect on LSAT score.
A TLDR of the study: LSAC asks testers to fill out survey at the end of every exam, with 9 different options for how that tester prepared for the exam. You can select more than one option, one of the options, option 9, is “No preparation.” Students who selected only option 9 performed only 1-4 points lower than any other combination of choices.
I believe the relevant data is in the tables on pages 22-23. LSAT scores are the numbers between ~148 and 152. Here’s the pdf: https://www.lsac.org/docs/default-source/research-(lsac-resources)/tr-11-03.pdf/tr-11-03.pdf)
Again, any insight is appreciated! I have my reservations about charging someone for tutoring services if it seems like it will largely be ineffective, but I’d love to understand the data better!
Also, there are obviously alternative explanations for the data that seem to exonerate it. For example, maybe students who are scoring far lower when starting, say around ~135, are much more likely to seek out tutoring or prep courses, and they are bringing their scores up ~15 points. Plausible?
