The term intelligence is very common as we hear it on the daily basis for different scenarios. But do you know what does it mean in reality? It is the ability to think from diverse mindsets, learn from experience, solve problems, and to gee new situations. The intelligence quotient (IQ) is considered the tool to measure intelligence according to the adjusted age. The most widely used IQ test for adults is the Wechsler Adult Intelligence Scale (WAIS).

Human intelligence consists of plenty of abilities like meat quality, observing and handling abstract concepts, and utilizing knowledge to manipulate the environment. This is the exciting side for the investigator to find the exact definition of intelligence. There are different opinions of investigators regarding intelligence. The most agreed perception of intelligence says that adaptation to the environment is the key to intelligence.

Measuring Intelligence: Standardization And The Intelligence Quotient

The objective of the intelligence test is to measure the intelligence factor in the person. Good intelligence tests are trustworthy, meaning that these tests are used to construct validity and measure intelligence rather than something else. Intelligence is one of the important differences of individual personality that is the reason that psychologists are investigating more accurate tests to evaluate accurate intelligence.

The level of intelligence of the human changes with age, as the three-year-old kid can easily multiply 195 by 34 is considered as intelligent but the 24-year-old who is unable to do so would be seen as unintelligent. Therefore, it is important to know the norms or standards to understand intelligence in the given population of people at a particular age. The standard of the test includes giving the task to a huge number of people of dissimilar ages to compute the average score on the test at every level.

Indeed, the intelligence tests must be standardized daily because the level of intelligence can be changed entirely in the population with time. Once we have the standardization of the test, we can get a clear picture of the average abilities of people of different ages.we can compute the exact mental age of the person and compare it with the real age.

The comparison of a person’s chronological person with the mental age is the measure of intelligence that is adjusted for age. The most simplistic formula is:

IQ = mental age ÷ chronological age × 100.

The most widely used intelligence test WAIS-IV consists of 15 different tasks, every task is designed to assess intelligence that includes spatial ability, arithmetic ability, working memory and general knowledge regarding the world. The score of WAIS-IV measures 4 major domains that are perceptual, working memory, processing speed, and variable. This test generally shows the correlation with the measures of daily functioning among the mentally retarded. If you want to measure your IQ level then you need to appear for such an intelligence test to check your mental ability as compared to the chronological age.
