How do IQ tests work, and which ones are the most practicle? Serious answers please...?

I don't know if there's one that is more practicle than another, but when I took one it was mostly just doing puzzles (timed) and some other random stuff like seeing a picture and stating what was missing, doing some math problems in my head, spelling, etc.  I think it varies with the different age groups though, I was 12 when I took it.\nWhen you get the answers back it says what subjects you're best at along with your general IQ.

Online IQ tests aren't that accurate. If you really want to know your childs IQ or if you are the one wanting the test, you will have to pay for it.\nHowever if you want a free IQ test...

IQ is something that measures our "intelligence" (it stands for "intelligence quotient") and a lot of it is down to your innate ability to process and retain information, work out complex problems etc. However, there are things you can do to stimulate your mind which may in turn help to improve your IQ score. \n\nRead! Yes, this is first because in order to improve your IQ you must read. But before you reach out for that worn-out paperback (a story you've read a million times) read a new book, a different book...a book from a completely different genre than what you're used to. You usually read mystery? Good, now go ahead and read some comedy. Only fiction? Go grab a biography. Read everything and anything (this includes articles, etc...). \n\nTry writing with your opposite hand. Some people claim that if you write with your opposite hand then your IQ goes up, because your brain is not used to writing with that other hand and is forced to work harder. However, if you're ambidextrous, that's great.. try writing with both hands at once, and try writing different things with different hands at once. \n\nWrite out long letters. Thinking about emailing your aunt that thank you letter? Forget it, write it out by hand. \n\nPlay video games. However, don't play that game you're always playing. Try a new game, something you've never played before. It will stimulate your mind and help you to think differently. \n\nWork on cryptology. This is when a message is written in codes and you try to figure it out...it's hard, but after a while it's fun. \n\nCrosswords and Sudoku..basically anything that stimulates the mind and that completely frustrates you because you just can't get it.

IQ tests vary within a range, generally- I have scored anywhere from 160-172, but I dont think it's a very broad measure of intelligence.  It would be equivalent to measuring high jump and sprint speed as a way to guage athletic ability in basketball.  It is related to intelligence, and perhaps gives a measure of potential, but isnt the thing itself.  I beleive that social intelligence, the ability to understand others, communicate your ideas and feelings, and achieve social goals are a better measure of the most important kinds of intelligence-and these are not measured in an IQ test.  The second most important ability I would rate would be judgement and long-term planning, also not measured in IQ tests.  There are a number of disorders, including FAS, in which the person's measurable IQ seems to be little effected, but they have very poor judgement and social connection.  If IQ were that important, then the mose successful, powerful, and joyful people would be those with the highest IQs, and studies have shown that these people generally fall in the range of 120-140.

Absolutely not. The tests aren't timed and the questions are not challenging enough, you should try the High IQ society...\nhttp://www.highiqsociety.org/iq_tests/\nThese tests are the most accurate online IQ tests available.

Look in the Yellow Pages for "Psychologists."  Many will offer IQ tests.\n\nIf you have ACT, SAT, GRE, or other tests, the Source link will let you estimate IQ from them.\n\nI'm quite interested in this subject.  You can contact me through the e-mail address in my profile.

oftenly we use IQ to measure people's intellegence.\nwhy are some people smarter than others??\n\n1. Genetics \nThe role of genes and environment (nature vs. nurture) in determining IQ is reviewed in Plomin et al. (2001, 2003). The degree to which genetic variation contributes to observed variation in a trait is measured by a statistic called heritability. Heritability scores range from 0 to 1, and can be interpreted as the percentage of variation (e.g. in IQ) that is due to variation in genes. Twins studies and adoption studies are commonly used to determine the heritability of a trait. Until recently heritability was mostly studied in children. These studies yield an estimate of heritability of 0.5; that is, half of the variation in IQ among the children studied was due to variation in their genes. The remaining half was thus due to environmental variation and measurement error. A heritability of 0.5 implies that IQ is "substantially" heritable. Studies with adults show that they have a higher heritability of IQ than children do and that heritability could be as high as 0.8, though it is probably not this high. The American Psychological Association's 1995 task force on "Intelligence: Knowns and Unknowns" concluded that within the White population the heritability of IQ is “around .75” \n\nConsiderable research has focused on biological correlates of g; see General intelligence factor and the section on brain size below. For example, general intelligence and MRI brain volume measurements are correlated, and the effect is primarily determined by genetic factors.\n\n\n2. Environment\nEnvironmental factors play a large role in determining IQ in extreme situtations. Proper childhood nutrition appears critical for cognitive development; malnutrition can lower IQ. Other research indicates environmental factors such as prenatal exposure to toxins, duration of breastfeeding, and micronutrient deficiency can affect IQ. In the developed world, there are some family effects on the IQ of children, accounting for up to a quarter of the variance. However, by adulthood, this correlation disappears, so that the cognitive ability of adults living in the prevailing conditions of the developed world is highly heritable.\n\nNearly all personality traits show that, contrary to expectations, environmental effects actually cause adoptive siblings raised in the same family to be as different as children raised in different families (Harris, 1998; Plomin & Daniels, 1987). Put another way, shared environmental variation for personality is zero, and all environmental effects are nonshared. Intelligence is actually an exception to this rule, at least among children. The IQs of adoptive siblings, who share no genetic relation but do share a common family environment, are correlated at .32. Despite attempts to isolate them, the factors that cause adoptive siblings to be similar have not been identified, though it could be related to parents choosing the type of children they will adopt. However, as explained below, shared family effects on IQ disappear after adolescence.\n\nActive genotype-environment correlation, also called the "nature of nurture", is observed for IQ. This phenomenon is measured similarly to heritability; but instead of measuring variation in IQ due to genes, variation in environment due to genes is determined. One study found that 40% of variation in measures of home environment are accounted for by genetic variation. This suggests that the way human beings craft their environment is due in part to genetic influences.

There are lots of on line sites where you can take an "IQ test".  They are interesting and fun to do, and tell us some things about ourselves, but they are not "real" IQ tests.  These tests tend to score higher than the real IQ tests.\n\nHere are some links you may find interesting and helpful.

IQ is a controversial thing. I personally don't believe you can measure a persons intelligence by looking at the scores of a test they did one day. Many factors could come into play such as the person being ill or not focused on the test. You can make yourself smarter just by exercising your brain like you would exercise any other part of you. Read or watch documentaries Test your maths skills and problem solving, look up random words in a dictionary to increase your vocabulary, look at encyclopedias and learn about history and other facts about the world. It's not as boring as it sounds. Especially once you get older and you can use your knowledge in conversations and your mathematics will be helpful in any form of occupation.

It depends what test and what kind of scores they generate.\n\nSome publishers like using percentiles, T-scores, or the most common, Standard Scores. The highest Standard Scores on a "real" IQ test usually do not go higher than 145.\n\nHere are the following standard score descriptions.\n\nlower than 69 Mentally retarded range\n79 to 70 borderline\n80 to 89 below average\n90 to 109 is average\n110 to 119 High Average\n120 to 129 Superior\n130+ Gifted range

Many things can be disputed about it. Firstly, IQ tests themselves are not accurate measures of intelligence. They only test certain skills and these skills are not exclusively innate. They can be taught. \nSecondly, it depends on social background, if a test asks about something the people taking the test have no knowledge about then they are unlikely to get the question wrong.\nThirdly, there are the social group of the people taking the test and bias. If he tested a group of white university students and compared the results with black prisoners or something then the results are going to be comprimised.\nMost importantly, the scientists who do these tests always have their own views and can easily mulnipulate the tests to get the results they want. There was a lecturer recently who said the black pupils in his class get lower marks than the white pupils. Proves nothing, he marks all their papers doesn't he?

I've been tested and told.\n\nBut IQ is no measure of one's chances for success in life. It's about believing in what you do no matter what they say. There is comfort in knowing, but also too much realism. Sometimes in life you must be ignorant to your 'actual' capabilities to progress. This applies to the full IQ spectrum!

It's not a matter of "good." Your IQ is slightly above average...so is 50% of the population!\n\nI have a student in my class (also 13) who tested at 145. That's pretty high, probably the highest IQ of anyone that I have met. But to speak with him and to work with him, you wouldn't know it. He seems quite average. Therefore, I doubt the veracity of the test. I don't know who tested him. I'm assuming it was at his previous school.\n\nPlease remember that these test must be preformed by a trained professional to be accurate.

The most valid and reliable way to do so is to take an individual IQ test given by a qualified psychologist. You can find a psychologist by looking in the phone book or by doing a yahoo search for the psychological association in your state. This is the best way to go if you want an IQ test for a serious reason, such as medical, legal or educational purposes.\n\nIf you don't need a professional test, there are several that you can take informally. Take the MENSA home test ($18) at http://www.us.mensa.org/AM/Template.cfm?Section=Mensa_Home_Test&Template=/customsource/cfauthnet_sim/forms/mht/form_mht.cfm\n\nLess reliable and professional tess are available online. Here is one example:\nhttp://www.iqtest.com/\n\nWhy do you want to take an IQ test? Think about what you want to know by this, and how knowing it will be helpful to you. Don't overestimate the importance of IQ in success or happiness. In general, motivation and effort make a much bigger impact on most people's lives!

Marilyn Vos Savant is on record for the highest with an IQ of 228.\n\nHowever, keep in mind that we have no records of the IQs of many influential people from history.\n\nIt is usually only measured up to 200 and is also based on your age.\n\nThere are many people who question how accurate IQ tests really are in determining intelligence.\n\nCheck my source if you want some more interesting IQ info.
