IQ 'measures' your intelligence for your age. An IQ of 100 means that you have the right intelligence for your age. A test like this one looks like it measureures ones reasoning ability. The ability to think objectively and logically (which i would guess the men are better at Please Register or Log in to view the hidden image! Please Register or Log in to view the hidden image! ). So for example a score of 150 would mean that one has a score higher then ones age by a half.So a 20 yr old has the reasoning capabilities of a 30 year old (1 + 1/2= 20 + 10=30). This is if this test actually measures intelligence or reasoning capabilities (logic) at all.
Tests on-line do not give you your IQ score. Frankly, any test that publishes its questions on-line is suspect. Valid IQ tests do not publish the questions. That's why you may have IQ scores all over the map when taking on-line IQ tests. Only a standardized IQ test can give you a good picture of what your IQ range may be. A test is standardized by looking at the responses to questions from a representative sample of people. A valid IQ rating typically remains pretty consistant throughout your lifetime after the age of 10 or so. IQ is only a measure of certain thinking skills that you may or may not employ in your day to day activities. IQ isn't the samething as knowledge.
