Methodology of Research and Statistical Techniques

Notes The fourth paragraph looks at social utility. We focus on the difference that the responses may
make and how the results will be used to affect change.
The fifth paragraph closes with a statement that the investigator is willing to answer any
questions or concerns. There is also a thank you statement.
The Envelope
The envelope must appear professional and be clearly distinguished from junk mail. It should
the correct size to hold the questionnaire without unnecessary folding.
Postage
First class mail is best because of its positive impression. Note too that first class mail is
delivered more quickly, is forwarded, and is returned to the sender if undeliverable. Interestingly,
stamps on the envelope rather than the postage meter seem to increase the response rate.

SASE
The self-addressed stamped envelop is essential, but only use the kind where pay only if the
envelope is used [requires postal permit]. This will cost more than first class mail by the piece,
but will save money because many of the envelopes will not be used.
Mail out Date
Early in the week works best, but avoid Monday because of mail buildup over the weekend.
Avoid holidays, December, and early January.
Follow-ups
A post card reminder/thank you jogs memories and reminds. Send after one or two weeks.
This should make the response seem more important. Text includes reminder of the respondent’s
importance and an invitation to get a replacement questionnaire if needed.

After the third or fourth week, send a letter and a replacement questionnaire with essentially
the same message.
After the sixth week, send a final, certified letter and replacement questionnaire [individual
researchers are unlikely to afford this step].
Check-in
It is important to have a logical, well ordered process to check in responses as they are
received and begin data coding.
Interviews
Interviewing is a technique that is primarily used to gain an understanding of the underlying
reasons and motivations for people’s attitudes, preferences or behaviour. Interviews can be
undertaken on a personal one-to-one basis or in a group.
They can be conducted at work, at home, in the street or in a shopping centre, or some other
agreed location.

Personal interview
Advantages:
• Serious approach by respondent resulting in accurate information.
• Good response rate.
• Completed and immediate.

• Possible in-depth questions.
