Do you usually score higher when you pass an IQ test for the second time?

Question

And what about Raven Advanced Matrix Test??

Answer 1

Every test has what is called the Standard Error of Measurement, a range around the score within which the score may vary (be different) but not be a significant difference.  If you score did not differ more the 15 points, there is a chance it could have have changed that much and not mean a thing.

Now, tell us, what have done done with your intelligence lately?  That is what is more important, what have you contributed to others.

Answer 2

There can be a "practice" effect with these types of tests.  This would be particularly true if you took the second test soon after the first.  The Ravens is a non-verbal measure of intelligence.  There would likely be some practice effect present if you took it for a second time.  However, you would not expect dramatic differences.

Answer 3

If you mean a free online one, then yes probably. The IQ test is a pretty flawed way to measure someones intelligence since it's biased toward learning disabilities like dyslexia or ADHD.

Answer 4

Well, you may score higher or lower the second time around, but most likely your scores will be within the same standard deviation.  They probably will not vary more than 10 points.
