In contemporary society, IQ is used for educational admittance, assessment of intellectual ability, and evaluation of job applicants. IQ scores have been shown to be associated with morbidity and mortality, parental social status, and biological parental IQ. By this definition, approximately 66% of the population scores between IQ 85 and IQ 115. The median raw score of a population sample is defined as IQ 100 and each standard deviation (SD) up or down is defined as 15 IQ points.


Intelligence quotient (IQ) is a total score derived from several standardized tests designed to assess intelligence. The IDR-IQ16 was compiled on the basis of peer-reviewed research, using metrics and data available to researchers.
