To maximize the validity and reliability, a pilot testing would be done. Moreover, study would include questions that support the investigation question and help to the expected results (Validity and Stability, n. d). Protection of human topics
The respondents would fill the set of questions anonymously. Their very own names may not be leaked out out. The questionnaire might also contain the statement that " All the responses will be treated secret and utilized for the purpose of research only”. No-one would get a clue that who took part in the study. Data collection
