Survey serves to determine general tendency, attitude, or opinions of a population quantitatively or in numerical values by working on a sample chosen from that population. The researcher draws inferences about the population based on the data collected from the sample. Survey can be employed to assess individuals’ attitudes, opinions, tendencies, and beliefs. Most frequent data collection tools for survey are questionnaires, scales, or interviews. Survey can be implemented once (cross-sectional) or at different times (longitudinal).
