how IQ is calculate

IQ, or Intelligence Quotient, is typically calculated using standardized tests designed to measure a person's cognitive abilities in areas such as logical reasoning, problem-solving, memory, and verbal comprehension. These tests generate a score based on how an individual performs compared to the average performance of others in their age group. The most commonly used IQ test is the Wechsler Adult Intelligence Scale (WAIS) for adults and the Wechsler Intelligence Scale for Children (WISC) for children. The average IQ score is set at 100, with a standard deviation of 15, meaning that most people score within one standard deviation of 100.
