In health services research, child and family research, education, and much of social sciences, the dominant data source is the survey. The key components of the survey and their evaluation will be introduced to students. The topics will include study design, sampling method, questionnaire formation, techniques of interviewing, data management, data analysis, and report writing. The course will request a semester-long project in which each student will design a survey to tackle a real-life survey issue and present the results at the end of the semester. The student will develop their abilities of independent thinking, analytical reasoning and problem-solving, and achieve the capacities of research planning and implementation.
