IQ numbers and percentages in Raven's advanced matrices?

[Per Eivind Jenssen]

I hope someone can help me out on this one:

I took a test at Mensa the other day and got myself an IQ-number. The test was called
Raven's advanced matrices. After the test I started to wonder about what IQ-number
relates to which percentage of the population?
The supervisor told me that with this test, an IQ of 148 is in the top 2% (limit for
Mensa membership), and an IQ of 156 gives a percentage of top 1%.
So which top percentage does 160, 164, 168 and further up belong to?
I got a score that placed me on the 164, but the number isn't comprehensive in itself,
a percentage is.
I'm not asking abuot this so that I can brag about it afterwards, I'd just like to
know :-) .

I thought that the Raven Advanced Matrices only gave you a percentile ranking - but I am probably wrong. Looking at the number=
s that Mensa gave you for the various IQ scores and percentile ranks (148 = 98%, 156 = 99%), it looks like they are using the same s=
tandard deviation for their IQ scores as is used on the Cattel IQ test (i.e. - standard deviation of 24 with a mean of 100). Since t=
his appears to be the case, I believe that your scores break down as follows:

148 = 98% (+2 SD)
156 = 99% (+2.333 SD)
160 = 99.38% (+2.5 SD)
164 = 99.62% (+2.67 SD)
168 = 99.77% (+2.83 SD)
172 = 99.87% (+3 SD)
175 = 99.91% (+3.125 SD)

In any case, it appears that your score places you among the very bright. In addition to Mensa, you may be interested in checki=
ng out Intertel (99%+). Information about Intertel can be obtained by wrinting to:

Intertel
P.O. Box 1083
Tulsa, OK 74101-1083
U.S.A.
(Note: Intertel, like Mensa, will only accept IQ scores on supervised tests of intelligence, and only certain tests are accepted - f=
or example:Stanford-Binet L-M, WAIS-R, WISC, Cattel, Raven Advanced Matrices, etc.)

There are other societies in existence which cater to even higher IQ individuals. The International Society for Philosophical E=
nquiry takes the top 99.9% - 150+ IQ on the Stanford-Binet L-M. If interested write to:

I hope that this information has been of some help to you. If I can be of further assistance, please feel free to email me at:

Cheers and welcome to Mensa!

With most IQ tests the raw scores are converted to IQ scores which are normally distributed. This is statisticians jargon.

On this test the Std. Dev. (another piece of stat. jargon) is about 24. Therefore, assuming a normal distribution, the scores you gave equate to percentiles as follows: 160 = top 6 out of 1000 164 = top 4 out of 1000 168 = top 2.5 out of 1000. Again, to figure out how to do this yourself, see any intro. test on statistics. It's also covered in some intro. psych. texts. A person with an IQ of 164 shouln't have any difficulty understanding this sort of material. Oh, one other thing. This particular test, which was probably the Cattell test, not the Raven's, uses an idiosyncratic standard deviation of 24. Almost all other IQ tests use standard dev- iations of 15 or 16. this means that an IQ of 164 on this test is the equivalent of one of 142 or 143 on one with a more conventional Std. Dev. Hope this helps. -------------------------------------------------------- * Brent Fredrickson * 0 28 9 26 30 11 7 20 32 17 5 22 34 15 3 24 36 13 1 Beating Roulette with the Biased Wheel Handbook http://www.avc-net.com/saros 00 27 10 25 29 12 8 19 31 18 6 21 33 16 4 23 35 14 2 --------------------------------------------------------

Did you take any of the on-line, computer-scored IQ tests? If so, how did
those scores correlate with the Raven's score (uncertain what standard
deviation those tests reportedly use, so uncertain what "ceiling" scores
mean) and with each other?

Did you know that there is an interesting, albeit
unintentional,association between the names of those hi-Q societies annd
the internet? A close friend, who goes by the nickname "The Incognito
Cogitator", tells me that he (or is this anonymous storyteller actually a
"she" in man's clothing?) used this association to save face, possibly to
save his hide....A long, long time ago, in a quasi-mechanized city far,
far away, he lived in a large urban tenament where mail was delivered with
minimal privacy. Alert neighbors noticed publications from several of
these societies heaped beside our hero's apartment door, and began asking
about them.
Our hero related that "Intertel" was an association dedicated to the
development of (often artificial) intelligence - whether this be
intelligence as defined by the artificial standards of a 30 minute test,
or admirable, real and true, "A.I". He related that "Integra", the name
of one journal, stood for the partial integration of facts in attempt to
formulate a theory - such incompleteness being symbolized by the only
partial spelling of the word "integra....te". He related that " Telicom",
another journal, meant "communication at a distance" and stood for the
emergent computer technology which would allow world-wide, rapid
communication between desktop users. Such explanations convinvced others
that he was merely a zealous, but forgivable, computer nerd - and not an
instantly despicable pseudo-intellectual snob.

an IQ test does not have standard deviations. the test's norm group had
a standard deviation. those WWW-based IQ tests are not normed, so it's
meaningless to talk about sd's so far as those are concerned.

I would like toknow my percentile ranking for my Ravens score. I am a woman 47 years of age and I scored 117 on the Ravens Matrices. The usual test....not the advanced test.

Can anyone figure that quickly? I wud appreciate it much and I do thank you if u are able to. :)
