Methods and Procedure
Data Gathering Procedure
The data for this research were collected using a survey questionnaire. The survey was created using suitable questions modified from related research and individual questions formed by the researcher. The survey was comprised of 20 questions, which were related to the participant’s perception regarding metrosexuality. In the questionnaire, Likert scale was used to determine if the respondent agreed or disagreed in a statement. After the professor validated the questionnaire, these were distributed to the second year preparatory dentistry students of Centro Escolar University – Manila. The researchers assured confidentiality of their survey sheets since the identities are not important. The researchers also understood that people’s consciousness may also affect their honesty and effectiveness in answering the survey, and so, the researchers gave people the option of being anonymous. Participants were given time to respond and then the researchers collected the surveys the next day. There were no incentives offered for participating in the research. Next, the researchers planned the questions that they would be asking to the interview. The researchers interviewed certain number of male students in the population regarding metrosexuality.
The group used Stratified Random Sampling. In this sampling technique, the group got random samples in a population which was composed of several second year preparatory dentistry sections. From each of these sections, the sample size was drawn proportionately, 20 students in each section, regardless of their gender.
Statistical Treatment of Data
In getting the sample size, the group used the Sloven’s formula which is, n= , N stands for the whole population of the second year preparatory dentistry students who were enrolled in second semester of school year 2011-2012, while e, stands for the margin of error, the researchers used 0.01 as the margin of error. The data collected were tabulated and analyzed. Analyses of data were guided by mean and percentage.
N = total population
e = margin of error
N = 400 second year preparatory dentistry students
e = 0.10%
