IQ TEST

Intelligence quotient – what is IQ?

At the very beginning, before starting the test, each of us should ask ourselves what is the intelligence quotient (IQ)?

Before you start the test, remember to provide yourself with the appropriate conditions for solving tasks in peace and quiet. Check also our logical puzzles to warm up!

START IQ TEST

IQ (intelligence quotient) is the numerical value of the intelligence test result. The IQ test result is a number that is used to describe a person’s level of intelligence. The specific score shows mental performance in the tests of perceptual reasoning, verbal reasoning, memory tests, and information processing speed. One of the basic components of our result is also age, which is compared with the mental age determined on the basis of the results obtained in the intelligence test.

Intelligence quotient – how are intelligence tests developed?

IQ tests are constructed in such a way that the definition of a group with an average IQ oscillates around 100 units with a deviation of 15 units. The conclusion is that obtaining a result between 85 and 115 units will define a group with an average IQ. In contrast, scores higher than 115 as above-average intelligence, and lower than 85 as lower-than-average intelligence.
From the above it can be concluded that the basic scale varies only in three numerical ranges:

  • < 85intelligence lower than average
  • 85-115 average intelligence
  • > 115above average intelligence

The problem, however, is more complex and the scale is much diversified, but the exact picture can be obtained by visiting the IQ Levels tab or taking part in an intelligence test. After completing the test and obtaining the result, it will be automatically assigned to a specific group corresponding to a given IQ.

Intelligence quotient – history of IQ tests.

The first tests for intelligence began in 1905 and were developed by the French psychologist Alferd Binet and the doctor Theodor Simon, which resulted in the creation of a test called “Binet-Simon Test”. This allowed in the initial phase to determine the intellectual level in children, i.e. the so-called mental age.
Following the spirit of the times and the development of society, intelligence tests have undergone a significant metamorphosis to adapt them to the prevailing reality, facts, vocabulary, etc.
The tests were used to identify the groups of people most in need of learning assistance. Ultimately, they were to show whether students keep up with their peers, lag behind or take the lead.
Currently, the “Terman-Merrill Scale” or the “Grace Arthur Scale” are used for the most frequently used tests. However, the most popular is the Wechsler scale because it has been strictly prepared for adults and children. Thanks to it, it is possible to evaluate, first of all, knowledge, concentration and cognitive functions.

Intelligence quotient – IMPORTANT

Each of us should bear in mind that each person has a different IQ, which is influenced by many factors. While the tests allow to determine the ability of logical thinking and abstract reasoning, unfortunately they do not allow to determine all the capabilities of the human mind.

Intelligence quotient – fun fact!

Albert Einstein

An outstanding physicist, creator of the theory of relativity and a Nobel Prize winner, he can boast one of the higher IQs – at the level of 162. This number is even one of the thresholds of intellectual genius that allows joining MENSA.
