This document discusses data collection procedures and determining what constitutes data in a study. It covers several key points:
1) The variables of study and their operational definitions determine what data is collected. Data collection methods depend on whether the research is qualitative or quantitative.
2) Qualitative research may use interviews, observations, and open questionnaires to collect in-depth data in a natural context. Quantitative research uses more structured observations and very structured interviews to collect brief, uniform data.
3) Common data collection methods include observations, interviews, questionnaires, tests, and elicitation techniques like judgments, translations, and recalls. The appropriate method depends on the research questions and goals.
