Latent variables, as created by factor analytic methods, generally represent "shared" variance, or the degree to which variables "move" together. Variables that have no correlation cannot result in a latent construct based on the common [[Factor analysis|factor model]].<ref>{{cite book |last1=Tabachnick |first1=B.G. |last2=Fidell |first2=L.S. |title=Using Multivariate Analysis |publisher=Allyn and Bacon |___location=Boston |year=2001 |isbn=978-0-321-05677-1 }}{{Page needed|date=November 2010}}</ref>
