Survey Method: Mail Surveys
A survey is a research method that involves gathering information from people through the use of a set of pre-determined questions. The main objective of a survey is to collect quantitative data or qualitative data from the target audience.
Mail surveys are a method of collecting data from a group of people using a set of pre-determined questions. This method of collecting data is the best option when you need to reach a large number of people, and the cost of collecting the data is a significant consideration.
Mail surveys are the best way for people to remain anonymous when giving their opinions. Respondents can complete the survey in their own time, and they do not have to reveal their identities. Furthermore, mail surveys reduce the chances of interviewer bias or the respondent feeling uncomfortable.
Therefore, option (C) is the correct answer.
