Superior intelligence. 90?110. Normal, or average, intelligence. 80?90. Dullness, rarely classifiable as feeble-mindedness. Iq was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an iq of 12/10 � 100, or 120. Further needed any help I will suggest you personal conversation.
