What Exactly is an IQ?

IQ stands for intelligence quotient. It is a score that is derived from a set of standardized tests to gauge intelligence. These tests come in many forms, using different types of questions and items to determine an individual’s intellect. The IQ classification is the practice where the IQ scores are labeled to be in the superior or the average category. On the basis of several cognitive abilities tests, the individual is given IQ scores. There have been two ways to determine the IQ level after the cognitive ability tests.

The first method is of the ratio IQ, which is entirely based on the mental age of the test taker while the second method used for IQ scores is the deviation IQ. Moreover, the results of the IQ tests would vary every time, even if the same person takes them over and over again. This is because the test taker does not use the same definitions and names for IQ scores classifications.
