RESEARCH METHODOLOGY

Detailed explanation-1: -In causal-comparative research, the researcher investigates the effect of an independent variable on a dependent variable by comparing two or more groups of individuals. For example, an educational researcher may want to determine whether a computer-based ACT program has a positive effect on ACT test scores.

Detailed explanation-2: -Causal-comparative research is a family of research designs used to examine potential causes for observed differences found among existing groups. Causal-comparative research is useful for the study of causes where experimental assignment or manipulation is infeasible, unethical, or in some way prohibited.

Detailed explanation-3: -"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-4: -An example of a comparative research title would have endless possibilities such as the difference between the poverty levels of countries, the salary between men and women, or even the religious aspects between communities.
