How do we know how many people had the same score?

Postby Hey-O » Fri Jun 25, 2010 5:31 pm

I have read on this site before that there is a way for to see how many people reach each score level. For instance how many people this year scored a 180 vs. a 167. I'm trying to find the post but I can't find it. Anyone know how to find this info on the LSAC website.

As far as I know, you can only extrapolate. For example, 173 is the 99th percentile. 150,000 tests are administered each year (IIRC), so approximately 1,500 people get a 173 or above. I guess you could figure out all the other scores and extrapolate even further, but...that might be overkill.

Of course, if the LSAC publishes actual numbers, then those would work better.

total # test takers x (100 - percentile)/100

I think?

I'm sure I saw the official LSAC numbers and where to get them somewhere on this site, but now I can't find it.

How do you know the total number of test takers?

Though, note, this doesn't separate out retakers.

This formula approximates the number of test-takers who get a given score or higher. To approximate the number of test-takers at a specific score it would look more like:

[total # test takers x (100 - percentile)/100] - [total # test takers x (100 - percentile of next highest score)/100]

All I care is that...

"In 2004, 10,370 blacks took the LSAT examination. Only 29 blacks, or 0.3 percent of all LSAT test takers, scored 170 or above. In contrast, more than 1,900 white test takers scored 170 or above on the LSAT. They made up 3.1 percent of all white test takers. Thus whites were more than 10 times as likely as blacks to score 170 or above on the LSAT. There were 66 times as many whites as blacks who scored 170 or above on the test.

Even if we drop the scoring level to 165, a level equal to the mean score of students enrolling at law schools ranked in the top 10 nationwide but not at the very top, we still find very few blacks. There were 108 blacks scoring 165 or better on the LSAT in 2004. They made up 1 percent of all black test takers. For whites, there were 6,689 test takers who scored 165 or above. They made up 10.6 percent of all white students who took the LSAT examination. "

Though, note, this doesn't separate out retakers.

So LSAC notes that for 2007-2008 "Most people take the test only once; last year 70.2 percent of the total
number of test takers took the LSAT just one time; 24.5 percent took the test twice; and approximately 5.3 percent took the
LSAT more than twice."

So for 2007-2008 142,331 tests were administered, which approx. only 99916 of those were first exams.

Although that 70.2% is probably not uniformly distributed throughout the score distribution. I would expect it to be much closer to 100% in the 170+ range.
