Your next paragraph should be a detailed extension of your methodology. The first part of your extended methodology should explain your data collection techniques and methods employed. It should be detailed but not overly wordy.
Your detailed extension of the methodology should serve the purpose of describing precisely all the methods you used to achieve your research goals. You may gain marks with including the materials, participants, research duration and procedures involved in the extended methodology.
Just like other chapters of the dissertation, methodology chapter writing requires careful approach. It takes you through surveys, interviews, observations, experiments and analyses. You will have to explain the methods used if your topic is new. In any case, the success of your research largely depends on its methodology.
Certain stages should be included into methodology chapter writing, like deciding the questions to be answered and considering potential problems in finding the answers. Dissertation methodology addresses research questions and focuses on the targeted goals. It should be concise, simple and well defined so that anyone without the knowledge of the subject could catch the idea easily.
