PERFORMING ORGANIZATION NAME(S) AND ADDRESS(ES): 8. PERFORMING ORGANIZATION REPORT NO.:Center for Naval Analyses CAB D0007188.A24825 Mark Center Drive Alexandria, Virginia 22311-1850 We examined data from a previous national administration of aptitude tests to a representative sample of youth known as Profile of American Youth (PAY 80). We regressed aptitude test scores on demographics and concluded that: "* Norming sample for aptitude tests must be representative of the target population with respect to age, race/ethnicity, gender, respondent's education, and mother's education. "* It is not necessary that the sample also be representative with respect to number of siblings in the household, degree O of urbanization, or census region. Although these factors may be correlated with aptitude scores, if the other five variables are representative, then these factors need not be representative.
