Sir

You can take but... Write your objectives and hypothesis properly to justify your research types... Also analysed with proper methods.. Thank you

Select Reserach design accordingly to research types and Take Sampling method properly

Mr. Rajdip

you can definitely take more than one research design because it depends on your objective and hypothesis which hypothesis or objective will fulfill from.

Yes Mr majumder you can take

You can blend different methods of data collection and analysis or various types of data in a single study, following either mixed methods research design, multimethod research design, or multimodal research design. Choosing a combination design relies on research aim and objectives and should be systematic. That being said, blending methods or data types in a research project is demanding in terms of time, effort, and money. The following references could be enlightening.

Good luck,

Major research design types usually include experimental, quasi-experimental, correlational, descriptive, qualitative methods. Doing 1 type of these research designs is often not easy, two types need to be done carefully, preferably with experience. It depends upon where you are in conducting research.

Doing a prospective study is more a description of the approach - is it a retrospective or prospective study of any of the above major quantitative types. The same is true of the cross-sectional approach. These are mutually compatible with each other and with the major quantitative types.

Good luck
