Free IQ Tests

Everyone has heard of an IQ test. The potential of the brain is called intelligence quotient or I.Q. These tests use the theories of unitary and multiple, which is believed to the two main theories when studying the brain.

Unitary refers to the part of the brain where the linguistic and mathematical capacities and confined them to that area. While the multiply theory include the parts of the brain that use visual/ spatial, musical/rhythmic, body/kinesthetic, interpersonal or intrapersonal development.

It has been determined that there is only three ways to increase your brains potential.

You first have to determine what you are good at. Very few people are good at everything. A person is considered intelligent whether their skill is derived from music, visual, body, or intrapersonal, intelligence.

Most people possess these skills and probably do not even realize it. If you are a creative person at heart, try your hand at writing, acting or singing.

You may be amazed at how well you do. Some people are born with in affinity for numbers; you may not think it is anything special, however others may. There are so many different areas in which you the potential excel.

Gymnastics, Dancing, building or designing, you do not know what you are capable of doing until you try. You get the most amazing feeling when you accomplish something you have never done before. If you do not even try, you are doing yourself a great disservice.

Very few people are classified as geniuses. A genius is a person who has extreme intelligence. Such people include Einstein, Mozart and Bach. These brilliant men accomplished greatness through their genius.

This is not to say that you have to be a genius to be successful. It simply means that you should use your brain to the fullest extent that you can. The more you try to improve yourself, the more your brain will benefit from it. When you utilize your brains potential you can achieve anything. Using your will power can point you in the right direction.

Broadening your horizons will also increase your brains potential. This is not to say that you should sit down and study the encyclopedia. When you study, you are acquiring knowledge through all five senses- touch, taste, see, smell, and taste.

You want to learn from your experiences in life, and experience everything in life. You cannot do that by studying. This is an excellent way to increase the potential of your brain.

New skills can be learned everyday. Talent comes in two forms, either you are born with it or you learn it. The brain is like a sponge, ready to absorb everything that is brought to it. The old adage that practice makes perfect holds true.

It is not difficult to maximize the brains potential. Many people everyday do it without even realizing it.

By simply reading a book, or singing along to your favorite song on the radio, you can increase your brains potential.

There are many IQ tests that one can take; however, many people question the accuracy of these tests.

Saqib Ali Ateel asked:


You might have heard that somebody has obtained very good IQ score. Some may even show you their certificates to prove that they have got more than 120 IQ score. Higher the score, higher the intelligence level is presumed. However, such claims and assumptions are baseless, false and misleading. The highest IQ test score in one IQ test may not be equivalent to an average score of another test.

A good IQ score is a relative term. The initial score obtained by answering the items correctly is called a raw score. It is useless unless interpreted in meaningful terms by following the established norms. Even when two scores are processed through the psychometric principles, you can’t ignore the following important issues before determining a good IQ score:

Name of the IQ Test

——————-

Unfortunately, the psychologists have not succeeded yet to develop a perfect system of comparing two IQ scores got from different IQ test. Naïve comparison of two digits, however higher they may be, can’t help you to determine a good IQ score. First of all you need to know on what IQ test on which the highest score was obtained.

Difficulty Level of the Items

———————————

The second problem to determine a good IQ scoring is the difficulty level of the test on which the claimed good IQ score was obtained. Your score will decline with the increasing difficulty level of the items being offered. It is possible that you get two different IQ score with two tests having same label. One reason for this variance would be the difficulty level of the items. The test developers vary the difficulty level of the test with the change of age, education and some other important factors.

Content Variance

——————-

You can find a number of tests with the same name but with different content. Even when you obtain 120 IQ score on an IQ test of verbal capabilities, you mayn’t claim the same level on another test of the same label containing mathematical items. General IQ tests try to develop items from all categories of intelligence but modern day testing industry is getting more specialized with every passing day. You need to consider content variation while determining any score a good IQ score.

Time and Age Differences

———————–

You may have got 120 IQ score in your fifth grade, 115 in sixth and 110 in seventh grade. Apparently, your intelligence level is decreasing with each passing year. However, the actual position may be entirely different for a number of reasons including the label of the test, the difficulty level or even difference in the content. You can’t be sure that your highest IQ score is your good IQ score.

Difference of Standard Deviation Units

——————————————-

Originally, the mental age (MA) was considered sufficient to measure your intelligence. It soon proved useless and the term of intelligence quotient (IQ) was introduced. It was nothing more than a simple ratio of the mental age to the chronological age, multiplied by 100 to eliminate decimals. A score of 100 was considered an average IQ score and any deviation could place you in the range of above or the below average population. The system worked well unless it was proved that standard deviation doesn’t remain constant throughout your life.

Now different IQ tests use different levels of standard deviation. It is possible that one test use a standard deviation of 15 and another of 20. In such situation two apparent equal IQ score can’t be interpreted into equal level of the intelligence. Thus determining a good IQ score becomes further difficult.

Composition of the Samples

——————————–

You may find guidelines about difficulty of test items, content, longitude differences and standard deviations in the manuals of the given IQ tests. However, you will rarely find the systems which helped the test developers to establish norms.

To establish norms, the test developers try to take a perfect sample of the subject population. However, there is so much variance in the general public that a perfect representative sample is almost impossible. The situation worsens when you try to compare IQ scores in different societies. Under the circumstances, no IQ score can be claimed as the best IQ score even when all other variables remain constant.

But What is Good IQ Score…?

——————————–

It is sufficient to prove that any digit is insufficient to be claimed as a good IQ score. All such claims are misleading, inappropriate and unhelpful. Similarly, no score can be claimed as bad IQ score. Unfortunately, the testing industry cares very little to remove this misunderstanding either by intent or inadvertently.
