What is IQ?

IQ stands for Intelligence Quotient, which is a numerical value of human intelligence. IQ scores are calculated from standardized tests. Intelligence comes in many forms and there are many types of IQ tests. However, in general, IQ tests are designed to measure a person’s reasoning ability. Reasoning ability refers to a person’s ability to use information and logic to answer questions or make predictions.

History of IQ Scores

Historically, IQ scores have been computed by dividing a person’s mental age score by their chronological age (physical age), then multiplying this number by 100. This was referred to as the “ratio IQ” and it tried to estimate a mental age. The current scoring method for IQ tests is called the “deviation IQ”. In this method a score of 100 means the test taker is at the median level of performance for his age group. That being said, the average person tends to score between 85 and 115.

How is IQ Calculated?

There are many ways to calculate IQ; however, two of the most common methods used in science are the Wechsler Adult Intelligence Scale and Raven's Progressive Matrices. The Wechsler Adult Intelligence Scale assesses four major components of intelligence: verbal comprehension, perceptual reasoning, working memory, and processing speed. Raven's Progressive Matrices assess abstract reasoning, which is regarded as a non-verbal estimate of intelligence.

Why should you care about your IQ?

Many studies have found a link between intelligence and performance in school or University, especially in areas such as science, mathematics, and English abilities. Additionally, many studies have found a link between intelligence and job performance. If you want to know more about your IQ you can take a Professional IQ Test

About the Test My Metrics IQ Test:

We developed our Professional IQ Test after extensive study into the latest intelligence research and IQ measurement methods. Our goal was to develop an accurate, valid, reliable IQ test that was Culture-fair and could easily be given online.

The TMM IQ Test is based on a classic intelligence assessment called Raven’s Progressive Matrices. Raven’s Progressive Matrices (RPM) was originally developed by John C. Raven in 1936 and is still widely used today. It is a nonverbal test, meaning test takers do not need to respond verbally. Therefore, the test is suitable for a broad age range of test takers, from 5-year-olds to the elderly. Since RPM assesses non-verbal aspects of intelligence, it can also be applied to various cultures without requiring any changes. Finally, the test is easy to administer and score.

The questions on the test all consist of a 3x3 matrix. Each matrix is missing an element in the lower right corner. Test takers must choose which image is the missing element in the matrix from 8 possible answers.
