This document describes and compares different research methods including interviews, questionnaires, focus groups, surveys, internet research, and library research. It outlines the type of data each method collects (qualitative, quantitative, primary, or secondary) and notes advantages and disadvantages. Interviews collect primary qualitative data but respondents could be untruthful. Questionnaires allow for first-hand opinions but responses may be false. Focus groups provide useful qualitative data but are expensive to conduct. Surveys gather responses quickly but participants may not answer truthfully. Internet research offers a variety of qualitative and quantitative secondary data but the right information is not guaranteed. Library research is a good source of historical information but incorrect sources could be found.
