RESEARCH METHODOLOGY

Detailed explanation-1: -An ex post facto research design is a method in which groups with qualities that already exist are compared on some dependent variable.

Detailed explanation-2: –also know as ex post facto (after the fact research); this research derives conclusion from observations and manifestations that already occurred in the past and now compared to some dependent variables.

Detailed explanation-3: -What is causal-comparative research? Also known as “ex post facto” research. (Latin for “after the fact”). In this type of research investigators attempt to determine the cause or consequences of differences that already exist between or among groups of individuals.

Detailed explanation-4: -Two other forms of quantitative research, which are not experimental due to lack of manipulation, are ex post facto (sometimes called causal-comparative) and correlational. Often both of these types are grouped into what researchers call non-experimental research or simply correlational research.

Detailed explanation-5: -The time series design uses multiple observations before and after an intervention. In some cases, experimental and comparison groups are used. In other cases where that is not feasible, a single experimental group is used.
