This method is used when members of one stratum in a
population are fewer compared to other stratums. Examplesof stratums are teachers and students, clerical personnel,
males and females.
Convenience Sampling The sample is selected, as the term applies, by convenience.
Because it requires less time, this method is best used in
preliminary research.

Before you list the questions to include in thequestionnaire, determine first what your PURPOSE is
for doing the survey.
The survey can be an effective research tool if the
purpose for doing it is CLOSELY ALIGNED with the
overall RESEARCH OBJECTIVES.
It would be such a waste of resources if the survey
results will not have any significant contribution to your
study.

TIPS ON WRITING A RESEARCH QUESTIONNAIRE
Provide clear instructions on how to complete the
questionnaire.
Start with interesting questions. The respondents will be encouraged and more likely to
complete the questionnaire if it is deserving of their
attention.
Ask clear questions.
Use simple words in asking questions so they can easily be
understood.
How to Write a Research Questionnaire
7/29/2019 Sampling Methods & Survey
19/31
Ask close-ended questions.
These questions give respondents limited response options.
They can be bipolar, multiple choice, rating scale or fill-in-the-blank types.
Because close ended questions provide for specific responses, they areeasier to tabulate.
Ask only one question at a time.
Questions that ask for more than one piece of information can be
confusing. For example, if the question is: in choosing a laundry detergent, do you
prefer one that is cheap and easily available?
It will be hard to decide whether the answer refers to cheap or easily
available or both.

TIPS ON WRITING A RESEARCH QUESTIONNAIRE

20/31
Group questions in a logical order.
If your questions jump form one topic to another, it may confuse
the respondent.
Make sure the previous question is reasonably linked to the next.
Ask the important questions in the first half of the
questionnaire.
There is no assurance that respondents will answer all the
questions completely.
Even if you get back a partially filled questionnaire, if you put in
the important questions first, there is a better chance that these
would be answered.

We are currently conducting a study on Network Gaming
Addiction and its Effects on Academic Performance incompletion of the course ENGL 303. We chose this subject
matter to validate the general perception that too much time
spent on playing the local network game Defense of the
Ancients (DOTA) causes the absences and failing grades of
the students of FEU-East Asia College. Although networkgaming is said to develop strategic mental ability, it seemingly
affects the academic performance of students in a negative
way.
