Research methodologies refer to the specific techniques and procedures that researchers use to conduct their studies and collect data. These methodologies can vary widely depending on the type of research being conducted, such as qualitative or quantitative research, and can include methods such as surveys, experiments, interviews, observations, and case studies. Researchers must carefully choose the most appropriate methodology for their study in order to ensure the validity and reliability of their results. Additionally, researchers must also consider ethical considerations and potential biases when selecting and implementing their chosen methodology.
