  5. Research Methods & Methodology • Differences

  6. Research Process • Formulating the research problem • Extensive literature survey • Development of working hypothesis • Preparing the research design • Determining sample design • Deliberate sampling, convenience, judgment • Simple random sampling • Systematic sampling
