IQ tests are sometimes used to assess childrenâ€™s cognitiveabilities. However, typical IQ tests draw on reading skills,which
may translate into lower scores for dyslexic children.Nonverbal IQ tests should circumvent this issue, allowing us toask
whether there is a relationship between reading skills andcognitive abilities in dyslexic children. The table below gives thereading
skill scores (on a standardized scale) and the nonverbal IQscores (also on a standardized scale) of 22 dyslexic childrenaged
7 to 10 years. Are the reading skill scores and nonverbalIQ scores significantly correlated in young dyslexicchildren?
