If the 10-year-old had a mental age of 8, the child’s IQ would be 8/ 10 × 100, or 80. A score of 100, where the mental age equals the chronological age, is average.Setting the male score at 100, Flynn found that women scored the lowest in Australia (99.5), but in the other 4 nations Raven's scores varied from 100.5 to 101.5.
