▁the ▁literature ▁for ▁datasets ▁containing ▁test ▁estimates ▁for ▁populations ▁or ▁groups ▁taking ▁both ▁the ▁AF Q T ▁and ▁tests ▁of ▁liter acy . ▁One ▁study ▁on ▁nine ▁groups ▁of ▁soldiers ▁differ ing ▁in ▁job ▁and ▁reading ▁ability ▁found ▁a ▁correlation ▁of ▁. 9 6 ▁between ▁the ▁AF Q T ▁and ▁reading ▁achiev ement ▁( St icht , ▁C aylor , ▁K ern , ▁& ▁Fox , ▁ 1 9 7 2 ). ▁Another ▁study ▁showed ▁significant ▁improvements ▁among ▁black ▁and ▁His pan ic ▁populations ▁in ▁their ▁AF Q T ▁scores ▁between ▁ 1 9 8 0 ▁and ▁ 1 9 9 2 ▁while ▁whites ▁only ▁showed ▁a ▁slight ▁decre ment ▁( K il burn , ▁Hans er , ▁& ▁Kl erman , ▁ 1 9 9 8 ). ▁Another ▁study ▁obtained ▁reading ▁scores ▁for ▁ 1 7 - year ▁old s ▁for ▁those ▁same ▁eth nic ▁groups ▁and ▁dates ▁( C amp bell ▁et ▁al ., ▁ 2 0 0 0 ) ▁and ▁found ▁a ▁correlation ▁of ▁. 9 9 7 ▁between ▁reading ▁scores ▁and ▁AF Q T ▁scores . ▁This ▁nearly ▁perfect ▁correlation ▁was ▁based ▁on ▁six ▁pairs ▁of ▁data ▁points ▁from ▁six ▁independent ▁population ▁samples ▁evaluated ▁by ▁two ▁separate ▁groups ▁of ▁investig ators . ▁According ▁to ▁Mark s , ▁" On ▁the ▁basis ▁of ▁the ▁studies ▁summar ized ▁here , ▁there ▁can ▁be ▁little ▁doubt ▁that ▁the ▁Ar med ▁Forces ▁Qual ifications ▁Test ▁is ▁a ▁measure ▁of ▁liter acy ." ▁ ▁However , ▁it ▁is ▁important ▁to ▁note ▁that ▁AF Q
