Since that time, EFA has become one of the most commonly used quantitative methods in many of the social sciences, including psychology, business, sociology, education, political science, and communications. To a lesser extent, it has also been utilized within the physical and biological sciences. Despite its long and widespread usage in many domains, numerous aspects of the underlying theory and appl 410 0$aUnderstanding Statistics 606 $aFactor analysis 606 $aPsychology$xMathematical models 606 $aSocial sciences$xMathematical models 615 0$aFactor analysis. 615 0$aPsychology$xMathematical models. 615 0$aSocial sciences$xMathematical models. 676 $a001.4/22 676 $a001.422 700 $aFabrigar$b Leandre R$01529709 701 $aWegener$b Duane Theodore$01529710 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910785725503321 996 $aExploratory factor analysis$93774137 997 $aUNINA
