answer 9 The WAIS is a standardized IQ test with a verbal and a non-verbal "performance"component, which separately measure language-related (e.g., vocabulary) and non-language related skills (e.g., reasoning about numerical quantity). The tests havebeen extensively normed, and the mean Verbal IQ (VIQ) and Performance IQ (PIQ)scores are uviQ=UPIQ=100, and both tests have a standard deviation of o=15. TheFull Scale IQ (FSIQ) is calculated by averaging these two subtests, and is used asan indicator of general cognitive ability. The FSIQ score also has a population meanof HFSIQ=100 and o=15.Statistical criteria are applied to these test scores to diagnose general cognitiveimpairment or a specific learning disorder like dyslexia (difficulty reading) ordyscalculia (difficulty with mathematical reasoning).7. Social services are available to those who meet a threshold of cognitive impairment.In some states, those with a FSIQ score of less than 85 meet this threshold. Whatproportion of the population in these states meets this criterion?8. A school district in WNY has 20,000 students in any given year. Of these students,those with very high or very low IQ scores (FSIQ > 1150or FSIQ < 85 ) are enrolledin specialized programs. How many students in the district would we expect are notenrolled in specialized programs in a given year?9. Specific learning disorders like Dyslexia are diagnosed by a discrepancy betweenthe scores on the IQ subtests. For example, a student with low VIQ score but anormal or high PIQ score might be diagnosed with a specific language impairment.In one school district, any PIQ or VIQ score above 86 is considered to be in thenormal range; scores below that cutoff are classified as "low". What proportion of thepopulation has a discrepancy diagnosis indicating a language impairment (a low VIQscore and a normal PIQ score)?
