A very swish Raven's IQ test

Post Reply New Topic

I took it in the end of January, when I should learn for exams
My result was 145, I sent it to my roommate, but she never told me about her result.
I find it quite easy, because there's no way to misunderstand some words

I got a 138. Official result is 130. Well, the test may be quite legit. It gives an idea of fluid iq which has good correlation with "g". Btw, I did horrible in school. I was classified as mentally retarted . Teachers called me "drug addict", "moron, "idiot","vegetable" LOL. However, I post graduated with a Engineering degree with specialization in Engineering design and also hold a Diploma in advanced computing. I work as a s/w engineer.

115, and I didn't get to finish the last 8 or so. The last few I did get to were really hard.

After doing it a second time I got 130.

Score was 105. Done in 10 mins with music and headphones on. Maybe if I took the whole 40 mins and took off my headphones would I get a higher IQ? Normally I don't trust these tests, I'm afraid to know if that's actually my real IQ score...

I think last time I got something like 110 on it (25 points higher than my last genuine IQ test, but almost exactly the equivalent of my score on the "matrix reasoning" subtest on that last IQ test).

They claim they normed this test with over 100,000 people. The WAIS normed their test with somewhere around 2000 individuals and the official Raven's matrices test normed it with somewhere under 10,000 individuals. Why not more individuals? 1) It's cost prohibitive and 2) You're not really adding any more significant statistical information given a representative sample size of 2000 individuals is descriptive enough for *any* population size.

So this tells me one thing: They're norming the test from online test takers: People like you and I. People who would likely have a higher IQ in the first place than a "real average person". From NBC's "What is your IQ?" test which tested the IQ of the public who was watching television and could be bothered to take an online IQ test, it was found the average IQ of the test takers was somewhere between 110-115.

So, your "real life IQ" is *likely* going to be higher than what this test states.

How much higher? For demonstrative purposes, let's presume the average "real life IQ" of people taking this test is somewhere around 110. That's the top 20th percentile.

Okay, I was going to delve into sophistry and say ... you take (your stated percentile)*(20/50) = (real life IQ percentile), but this will also depend on the distribution's characteristics. Furthermore, your projected "real life IQ" is not *necessarily* the same thing as your real life IQ as this measures one particular ability, and its correlation with "G" is not necessarily that high. Presumably it is, but to verify it requires factor analysis and correlation studies with other highly-G loaded tests. Also, another problem is that the correlation tends to loosen quite a bit into the high range of IQ scores, so even if the test had a high correlation with 'G', it doesn't necessarily retain that high correlation in the high range as higher scores tend to tap one or a few increasingly specialized abilities that aren't as 'generally representative' of fluid reasoning as G is.

Btw, my tested "this thing's IQ" is 130 and my WAIS IQ was 145.
