Intelligence quotient (IQ) is a measure of a person's cognitive abilities, specifically their ability to reason, solve problems, and think abstractly. The concept of IQ was first introduced in the early 20th century and has since become a widely used tool for assessing cognitive ability and predicting future academic and occupational success.

The intelligence quotient scale is a way of measuring IQ by assigning a numerical value to an individual's cognitive abilities. The most commonly used IQ scale is the Wechsler Adult Intelligence Scale (WAIS), which is used to test adults and older adolescents. The WAIS consists of a series of verbal and performance subtests that are designed to measure different aspects of cognitive function.

There are several different ways in which IQ scores can be interpreted, but the most common method is to compare an individual's score to the scores of others in their age group. This is done by calculating the number of standard deviations that an individual's score is above or below the mean score for their age group. For example, a score that is one standard deviation above the mean would be considered above average, while a score that is two standard deviations above the mean would be considered very high.

It is important to note that IQ scores are not fixed and can change over time. Factors such as education, experience, and even nutrition can all impact an individual's cognitive abilities and, in turn, their IQ score. Additionally, it is important to recognize that IQ tests are just one way of measuring cognitive ability and should not be the sole determinant of an individual's potential or worth.

In conclusion, the intelligence quotient scale is a tool used to measure cognitive ability and is often used to predict future academic and occupational success. While IQ scores can be a useful measure of cognitive ability, they should not be the sole determinant of an individual's potential or worth, and can change over time due to various factors.

It is disputed whether these changes in scores reflect real changes in intellectual abilities. The average mean score is typically 100. The higher the IQ the better. In Oscar Buros ed. Some limitations of attempts to divide intelligence into multiple domains may be related to measurement limitations, rather than the actual nature of individual abilities.

Sometimes intelligence tests are supplemented by additional measures of special ability, such as Visual Motor Integration, Wide Range Assessment of Memory and Learning, measures of information processing such as the Detroit Tests of Learning Aptitude—3, or language tests, to describe a child's skills or deficits further.

Seventh Mental Measurements Yearbook. Environmental deprivation has classically been cited as the cause of cognitive delay in this group, although this is now criticized for being too simplistic.

Kaufman and Nathan Brody and statisticians such as Bernie Devlin argue that there are insufficient data to conclude that this is because of genetic influences.
