It explains the meaning and necessity of defining a research problem, sets out research objectives, motivations, and types, and contrasts research methods with methodology. The lecture introduces research design, sampling design, measurement and scaling, primary and secondary data collection, and outlines key processing and analysis concepts, including statistics and hypothesis testing.","Research Methodology  \nMethods and Techniques  \nLecture 001  \nYounus A.
