mean = SD = ranges <70 70-79 80-89 90-109 110-119 120-129 130+
mean = 100 SD= 15

1= verbal comprehension scale
2= perceptual reasoning scale
3=working memory scale
4= processing speed scale
define
verbal comprehension index

moderate

profound
mild = 55-70 moderate = 35-54 severe = 25-34 profound = below 25
