RESEARCH METHODOLOGY

Detailed explanation-1: -There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause-effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.

Detailed explanation-2: -Diagnostic research is one of the research design types that aims to examine the underlying cause of a certain situation or phenomenon.

Detailed explanation-3: -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.

Detailed explanation-4: -Experimental research allows the researcher to control the situation. In so doing, it allows researchers to answer the question, “what causes something to occur?” Permits the researcher to identify cause and effect relationships between variables and to distinguish placebo effects from treatment effects.
