cont....with intelligence (psychology notes) WAIS

Wechsler Scales of Intelligence (WAIS) - the advantage of the WAIS is that it has a provision in addition to an overall IQ and number of separate scores for different intellectual functions.  It has eleven subtests divided almost equally into verbal IQ and performance IQ.  The average IQ is 100 and one's overall IQ reveals the distance --above or below--one is from the mean.  This is called the Deviation IQ which is the distance between one's score and the general population's scores.   As mentioned, the WAIS has eleven subtests - five performance tests and six verbal tests.  Each subtest yields a separate score and combines in a composite overall IQ  score.
