RESEARCH METHODOLOGY

Detailed explanation-1: -Out of the given options, the N-experimental is not a research design.

Detailed explanation-2: -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-3: -Correlational research is considered non-experimental because it focuses on the statistical relationship between two variables but does not include the manipulation of an independent variable.

Detailed explanation-4: -In nonexperimental designs, the groups already exist and the experimenter cannot or does not attempt to manipulate an independent variable. The experimenter is simply comparing the existing groups based on a variable that the researcher did not manipulate. The researcher simply compares what is already established.

Detailed explanation-5: -Descriptive Research Design. Correlational Research Design. Experimental Research Design. Diagnostic Research Design. Explanatory Research Design.
