How do you find the theory of theoretical framework?

Strategies for Developing the Theoretical Framework

  1. Examine your thesis title and research problem.
  2. Brainstorm on what you consider to be the key variables in your research.
  3. Review related literature to find answers to your research question.
  4. List the constructs and variables that might be relevant to your study.

How do you find the theoretical framework?

In a thesis or dissertation, the theoretical framework is sometimes integrated into a literature review chapter, but it can also be included as its own chapter or section. If your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

What is the composition of mosquito repellent?

The major components of the oil were fenchone (6.0\%), piperitone oxide (32.4\%), piperitenone (3.0\%) and piperitenone oxide (41.5\%). The repellent activity of the volatile oil at different concentrations was measured by the protection period against the bites of Anopheles stephensi and Culex fatigans.

The selection of a theory should depend on its appropriateness, ease of application, and explanatory power. The theoretical framework strengthens the study in the following ways. An explicit statement of theoretical assumptions permits the reader to evaluate them critically. The theoretical framework connects the researcher to existing knowledge.

How do you choose the theories you choose to investigate?

The theories you choose to investigate will provide direction to your research, and you can continue to make informed choices at different stages of the dissertation writing process. The theoretical framework bases are the scientific theories that justify your research; therefore, you must use them appropriately for referencing your investigation.
