Survey design is an iterative
process involving

These stages occupy most of
the time
Before finally issuing the

Designing a questionnaire
Design is important for useful data
 How will you analyse the data?




Qualitative
Quantitative
This will affect the types of question you use


Open - respondents can give their opinions, feelings
etc. in their own words.
Structured - range of responses is restricted.
Open questions
Wide range of views
 Richness of data
 Generally best suited to qualitative analysis


Has its own methods of verification.
Non-uniform responses
 Best suited to small scale or pilot surveys.
 Useful for developing fixed response items

Structured question
Constrained choice
 Involved standardised responses
 Best suited to quantitative analysis



May miss important issues



Usually using statistics
Add qualitative item(s)
“Are there any other points you would like to add?”
Suitable for large samples
Some practical issues

How many questions?



Layout



Well spaced, clearly laid out
Easy to follow
Length of questions


Too few - not enough data
Too many - goes in the bin!
Not too long - break into shorter questions
Pilot questionnaire helps resolve issues
Ethics
 Critical
to survey research.
 Should I be asking this?
Confidentiality
 Sensitive information
 Personal information
 Raising expectations?

 Anonymity
of respondents
 Data protection act.
Types of structured question

than the direct question What is your age?
Quantity & Ranking

Quantity: How many times did you eat chips last
week?
Ranking: Place the following in the order of
importance, number 1 being the most important
 A well stocked library



Leading questions e.g.


You do think this is a poor module don’t you?



do not assume all students are on full time courses
Do you go to aerobics and go jogging?


What is your age?
In summary

Formulate a hypothesis


Pilot your survey



Open questionnaire to identify issues
Test and revise your questions
How will I analyse the data?



How does this question contribute?
Qualitative or quantitative?
Which statistical tests?
What are the ethical issues?
