RESEARCH METHODOLOGY

Detailed explanation-1: -This intervention is caused by manipulation of the independent variable. The use of descriptive research is done when you want to observe a certain group or an individual while experimental research is used when you have a theory and you want to test it out by experimenting on the variables.

Detailed explanation-2: -A descriptive research design can use a wide variety of research methods to investigate one or more variables. Unlike in experimental research, the researcher does not control or manipulate any of the variables, but only observes and measures them.

Detailed explanation-3: -Experimental manipulation describes the process by which researchers purposefully change, alter, or influence the independent variables (IVs), which are also called treatment variables or factors, in an experimental research design.

Detailed explanation-4: -Case study method The other reason why case studies are not a reliable way of conducting descriptive research is that there could be an atypical respondent in the survey. Describing them leads to weak generalizations and moving away from external validity.
