Research methodology simply refers to the practical "how "of a research study. More specifically, it's about how a researcher systematically designs a study to ensure vaild and reliable results that address the research aims, objectives and research questions. Within any formal piece of academic research, you'll find a research methodology chapter or section which covers the aspects mentioned above. Importantly, a good methodology chapter explains not just what methodological choices were made, but also explains why they were made. In other words, the methodology chapter should justify the design choices, by showing that the chosen methods and techniques are the best fit for the research aims, objectives and research questions. The choice of which data collection method to use depends on your overall research aims and research questions, as well as practicalities and resource constraints For example, if your research is exploratory in nature, quelitative methods such as interviews and focus groups would likely be a good fit. Conversely, if your research aims to measure specific variables or test hypotheses, large-scale surveys that produce large volumes of numerical data would likely be a better fit.
