• Questionnaire answered by the informant.

     From all 4 methods, classified according to the relationship between the data collector and the informant can be separated into 2 main methods:

     1. Interview from a person directly. Researcher or interviewer will inquire directly from the interviewee. The interview method may be used by phone but there is a limitation that it is not possible to ask a lot of information.

     2. Send the questionnaire to the researcher. It is an economical method but there are limitations that can’t be used with people with low education or no education. Although being able to read the questionnaire may cause a misinterpretation.

     The first method will cost more than the second method but there will be less difficulty in answering the problem. Because the interviewer can inquire and give a description of the problem to the researcher In case of not understanding the question.
