on the researcher’s readings, previous studies, professional literature, published and
unpublished thesis relevant to the study. In the preparation of the instrument, the

For instance, statement describing the situations or issues pertaining was toned down
to accommodate the knowledge preparedness of the respondents. Open-ended options
were provided to accommodate to free formatted views related to the topics or issues. In
this way, the instrument is authorized to obtain valid responses of the students.
Preference for the use of the structured questionnaire is premised on several
research assumptions such as a) cost of being a least expensive means of gathering data,
b) avoidance of personal bias, c) less pressure for immediate response, and giving
the respondents a greater feeling of anonymity. In the end, it encouraged open responses
to sensitive issues at hand. In addition the instrument was validated by few consultant and
former professors before it laid on to the study.
Data Gathering Procedure
The first step before going to the testing proper is to make a request
letter. Upon approval, the researcher retrieves the request letter. The Principal, as well as
class advisers and other faculty members were selected in the administration.
In administering the questionnaire, the researcher was use the time allotted for vacant to
avoid distractions of class discussions. The student responses were given enough time to
3. answer the questions. After data gathering, the researcher now collected it for tallying the
scores and to apply the statistical treatment to be used with the study.
Treatment of Data
The responses made by students describing their socio-demographic profile,
Preference of choosing their career, and anticipated problems were presented. For

To know if there is a correlation between the independent and dependent variables
Pearson Product Moment of Correlation Coefficient was utilized with 0.05 level of
significance.
