Full Form of IQ
IQ stands for Intelligence Quotient. It is a measure used to assess human intelligence through standardized testing. Here are some key points about IQ:
Purpose: IQ tests are designed to evaluate various cognitive abilities, including reasoning, problem-solving, and understanding complex ideas.
Calculation:
- The IQ score is typically calculated based on the ratio of an individual’s mental age to their chronological age, multiplied by 100.
For example, if a 10-year-old child performs at the level of a 12-year-old, their IQ would be calculated as (12/10) x 100 = 120.
Scale:
- The average IQ score is set at 100.
Scores are generally categorized as follows:
- Below 70: Considered below average or intellectual disability
- 70-85: Below average
- 85-115: Average
- 115-130: Above average
- 130 and above: Considered gifted
Types of Tests:
Various standardized tests assess IQ, including the Wechsler Adult Intelligence Scale (WAIS) and the Stanford-Binet test.
Controversies:
- IQ tests have faced criticism regarding cultural bias and their ability to encompass the full range of human intelligence.
Understanding IQ can provide insights into cognitive abilities but should be viewed as one of many measures of a person’s capabilities.
