What is IQ 


What is IQ?

I.Q. (intelligence quotient) in general, is an assessment of your ability to think and reason. IQ score is a standardized way of comparing this ability with the majority of people the same age as you are. A score of 100 means that compared to these people in your general age group that you have basically an average intelligence. Most psychologists would say those scoring in a range of 95 to 105 are of a normal intelligence or have an average IQ. Actual IQ score may vary plus or minus five points since it is very difficult to get an IQ score with complete accuracy. Keep in mind, there are many outside factors that may have a negative impact on your score. For instance, if you are not feeling well at the time of taking the test. Or perhaps you are distracted by something on that particular day. These things may affect your score. Additionally, IQ is not the be all end all of a person's abilities in life. IQ score fails to measure things such as manual dexterity (obviously), musical talent, and a slew of other abilities that may lead one to many different successes in life. However, your score on an IQ test will give you a pretty accurate indication of the ability you possess to think, reason and solve problems which can often be critical in many phases of your life.


The Advantages of IQ Tests

Much is made of a person's intelligence quotient (IQ). This number is supposed to determine a level of intelligence that each person posses. Almost everyone has, at one time in his life, taken an IQ test. While some critics denounce the use of IQ tests, they actually have many benefits and advantages over other forms of intelligence measure.


Testing Behaviors

One of the best things about IQ tests actually has nothing to do with intelligence. The test is a very accurate measure of human behavior due to the way the test is set up. The IQ test is one of the best ways to get an overall view of human behavior which can then be analyzed by age, race, and gender. This allows behavioral scientists to study trends in various groups as they take the test. Analyzing the data in this way provides these scientists with insight into how different groups of people learn based on their test results. This insight helps educators to tailor their teaching to get the best results.


Academic Achievement

The IQ test is often given to children at the beginning of their school career as an indication of how well they will do in their educations. The test is used as an indicator that allows school districts and teachers to determine what type of classroom setting to place a child in. A child who scores high on the test may be placed in an advanced learning situation, which will take care of her educational needs. A child who scores low, however, will be able to be placed in a classroom situation that will give her the most benefit. Without this test, children may be placed in classroom not suited for them.


Societal Benefits

Since the IQ tests can identify the potential for academic achievement, schools can begin to develop students in a way that takes advantage of their natural talents. If a child's talents are developed correctly, he has the potential to maximize his skills to be beneficial to society. For instance, if an IQ test shows that the child has some talent in math and science, those interests and talents can be developed to help the child get into a medical, research, or engineering field. This helps a society keep a steady supply of people who can provide benefits, making life better for all of their citizens.


Results of an IQ Test

According to the Stanford-Binet Intelligence Scale Fifth Edition, an average IQ scoreis any score within the range of 80-119, where scores closer to 80 are considered Low Average, and scores closer to 119 are considered High Average.



IQ scale meaning

What does an IQ score mean? What is the average IQ? After taking an IQ test, you might need some help with the interpretation of your IQ score to understand what your IQ score actually tells you. Is your iq average? Do you have a genius IQ score? The table below shows an IQ scale chart that gives a clear overview of the IQ score ranges as derived from Resing and Blok (2002)1. The table distinguishes different categories based on the height of your IQ score, meaning you gain some understanding of your capacities.

80-8915.7Below average intelligence
70-796.4Cognitively impaired


About 2% of the population has an IQ score lower than 69. Such a low IQ score often is hard to measure using a regular intelligence test. Very high IQ scores are also hard to determine accurately. This is because you need a lot of reference measurements to determine a specific score reliably. As very high and very low IQ scores simply do not occur often, it is hard to form such a reference group.
