Primarily, the researcher conducted field interviews with respondents with the use of an interview
schedule. The interview schedule survey forms were pre-tested to randomly selected group of residents
within the community. The residents were not included as respondents for the actual survey. The pretesting
supervised by the researcher cleared any ambiguous questions which were consequently
improved and corrected accordingly. During the actual survey, an initiated one-on-one survey was
employed. The first household served as the first respondent and starting point for the stratified random
sampling. From the first house, the researcher counted from one (1) to two (2) to identify the next
household to interview. This continued until the researchers reached the last house and completed the
sample size. To validate answers that were not elaborated in the questionnaire, key informant interview
was employed.
