Information collection method based on sending printed questionnaires to predetermined respondent addresses, which are then returned to the center by mail after being filled out.
The mail method involves sending pre-designed and printed questionnaires to predetermined participant addresses. In this process, the research questions are printed on paper and mailed to the participants, who then fill out these forms and return them to the specified address. This method is particularly effective in regions or demographic groups with limited digital access.
The mail method allows participants to complete the survey at their own convenience in a comfortable setting. Participants can carefully review the survey and thoughtfully consider their responses, which can enhance the quality of the answers and provide more considered feedback. Additionally, the postal return of completed surveys ensures a traceable and organized data collection process.
Despite some cost and time disadvantages, such as printing, mailing, and waiting for returns, the mail method remains a reliable and effective data collection technique for certain demographics or regions. It is particularly suitable for older participants or those in rural areas who may be more accustomed to non-digital methods.
