3. Definition
Questionnaire is a set of questions asked to the target
respondents. Both open and close-ended questions can be
used in the design of the questionnaire to collect data.
In questionnaire design the different types of data which
can be used are; nominal, ordinal, interval and ratio
scales.
4. What are the different scales?
NOMINAL: Label objects (e.g. yes/no, gender)
ORDINAL: Indicate only relative size differences between
objects (e.g. purchase frequency)
INTERVAL: Use descriptors that are equal distances apart
(e.g. measuring temperature)
RATIO: Have a true zero point (e.g. rupees spent)
5. Characteristics of a good questionnaire
1.
Should be concerned with specific and relevant topic
2.
Should be short
3.
Directions and wording should be simple and clear
4.
Questions should be objective
5.
Early questions should be simple in design, friendly and easy to respond;
on the other hand; they should convey the theme of the study to the
respondent.
6.
The questionnaires should begin with an effort to awaken the respondents’
interest. Important target questions should be asked in the middle of
the opinion survey.
7. Embarrassing questions, presuming questions and hypothetical
questions should be avoided
6. Continued
8. Should be presented in a good order
9. Should be attractive, neatly printed and clearly arranged.
10. All the questions related to personal information (name,
income, phone, address etc.) of the respondents should be either
optional or asked in the last section of the questionnaires.
11. Open ended questions should be placed in the later part of the
questionnaire and deliberately kept to the minimum.
7. What are open and close-ended questions?
For
open ended questions the researcher does not provide any options to answer. Questions are
open to any descriptive response.
Example:
Q. what do you do to keep yourself healthy?
_______________________________________________________
_______________________________________________________
_______________________________________________________
_______________________________________________________
Close ended questions have definite options and they are easy to respond
Example: (Tick the appropriate options below)
Q. what do you do to keep yourself healthy?
a) by running/jogging more than 3 times weekly
b) by brisk walking daily
c) By biking daily

9. Functions of questionnaire
DESCRITION:
The questionnaire provides description about
age, sex, marital status, occupation, income,
religious affiliation, etc.
MEASUREMENT:
Measurement of individual and/or group
variables like personal habits, reading, watching

10. Questionnaire as instruments
Most
survey research relies on the
use of questionnaire to measure
variables
Demographic
The
variables
accuracy and precision of
questionnaire requires expertise and
care in their construction
11. Demographic variables
Demographic
variables are used to describe
the characteristics of the people who are
surveyed.
Measures
such as race, ethnicity, age and
socio economic status.
The
accuracy and precision of questionnaire
as survey research instrument depends upon
the expertise and care that go into their
construction
12. Preferences and attitudes
Individuals
preferences for certain
things and attitudes.
For
example use of certain perfume,
Attitude toward smoking in Public
places, eating of certain type of
food.
13. Self report scales

attitude about items presented on the
scale
e.g. Games, cold drinks like Pepsi, political
leaders
To determine differences among people on
some dimensions presented on the scale
e.g., reading more or less, amount of stress
14. Reliability
Reliability refers to the consistency of measurement.
Reliable test should yield similar(consistent) results
each time it is taken
Common method: test- retest reliability
FACTORS AFFECTING RELIABILITY:
Number of items
Variability
Condition in which the questionnaire is administered
15. validity
It refers to the truthfulness of a measure
Does it measure what it intends to
measure?
Assessing validity: Construct validity
Extend to which it measure the theoretical
construct it is designed to measure.
16. Constructing a questionnaire
Deciding type, writing a draft, pretesting, concluding with
specific procedures.
STEPS:
1.
Decide what information should be sought
2.
Decide what type of questionnaire should be used
3.
Write a first draft of the questionnaire
4.
Reexamine and revise the questionnaire
5.
Pretest the questionnaire
6.
Edit the questionnaire and specify the procedures for its use.
17. ORDER
OF THE QUESTIONS:
Begin with simple and general questions
No sensitive and embarrassing questions at beginning
Move from general to specific in logical manner
Sensitive questions at the end
Demographic data should be obtained at the end of self
administering questions
Use funnel sequence: Start with broad questions and gradually
narrow down to the specific questions related to the topic.
18. The structure of the questionnaire?
Opening
• Show Courtesy
• Awaken the respondents interest on the topic
Early
Questions
• These should be simple, friendly, close ended, easy to
respond questions & should convey the theme of the
study
Middle
Questions
• Ask the Target Questions
Late
Questions
• Ask optional questions like name, age etc along with
open-ended question here
Closing
• Build relation, Keep scope for future meetings, show
gratitude to the respondent for responding, leave on
a positive note
19. conclusion
Questionnaire are the main and easy way collecting
data
But the questionnaire must be highly reliable and
valid.
Using standardized questionnaires will give us the
appropriate data and will yield a valid study
One must follow all the basic guidelines and methods
of constructing a questionnaire and test it before using
it.
