RESEARCH METHODOLOGY

Detailed explanation-1: -"An important difference between causal-comparative and correlational research is that causal-comparative studies involve two or more groups and one independent variable, while correlational studies involve two or more variables and one group.” (Gay & Airasian, 2000, 364).

Detailed explanation-2: -In causal-comparative research, the research subjects are already in groups because the action or event has already occurred, whereas subjects in experimental research designs are randomly selected prior to the manipulation of the variables.

Detailed explanation-3: -One principal difference between comparative research and experimental research is that the comparative researcher does not subject a group to a treatment, but rather observes a group that either by choice or circumstance has been subject to a treatment.

Detailed explanation-4: -Correlational research, and causal–comparative research is sometimes treated as a type of descriptive research because it too describes conditions that already exist. Correlational studies and causal–comparative studies help to identify variables worthy of experimental investigation.
