RESEARCH METHODOLOGY

Detailed explanation-1: -Correlational research design involves correlation between two variables and causal comparative research design involves comparing two groups in order to explain existing differences between them on some variable or variables of interest.

Detailed explanation-2: -For comparative studies, the design options are experimental versus observational and prospective versus retrospective.

Detailed explanation-3: -Descriptive research aims to accurately and systematically describe a population, situation or phenomenon. It can answer what, where, when and how questions, but not why questions. A descriptive research design can use a wide variety of research methods to investigate one or more variables.

Detailed explanation-4: -Comparisons with Experimental Research Unlike correlational research, both experimental research and causal-comparative research typically compare two or more groups of subjects. Research subjects are generally split into groups on the basis of the independent variable that is the focus of the study.

Detailed explanation-5: -Experimental research, often called true experimentation, uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study.
