Under the heading method and design in your research proposal regardless of the method/approach used qualitative, quantitative, or mix methods, you will need to discuss the data collection instrument (tool) you propose to use to gather data. Instrument is the general term that researchers use for a measurement device (survey, questionnaire, test, interview, observation, etc.). Discuss the instrument you intend to use in your research proposal and how you intend to address the instrument’s validity and reliability noting the different types of each.
