Conceptual framework: “…identifies a set of variables and relationships that should be examined in order to explain the phenomena”; “…need not specify the direction of relationships or identity critical hypotheses”
Theoretical framework: “…joins theory to some specific state or action that is desired or is to be taken”; seen as “… more specific and concrete than theory, and can usually be shown in a diagram or picture… [AND] should contain specific elements derived from theory that either predict action or outcome, or contribute in some way to achieving the desired change.”
