“A formal list of questions are called
questionnaire”.
“A questionnaire is the vehicle used to pose
the questions that the researcher wants
respondents to answer”.
DR. AMITABH MISHRA 5
DR. AMITABH MISHRA 6
In questionnaire method data are collected by
asking questions to the people who are thought of
having desired information.
Questions may be asked in written or in person.
Translates the research objectives into specific
questions
Standardizes those questions and the response
categories
Fosters cooperation and motivation
Serves as permanent records of the research

Can speed up the process of data analysis.
Can serve as the basis for reliability and
validity measures.

1. Many marketing problems can be studied only by asking
questions.
Ex- knowledge , opinion, motivation, intention etc.
2. Questionnaire are faster and cheaper than observation.
Interviewer can proceed from one interview to another with
no wait in between.
DR. AMITABH MISHRA 9
3. Some events that take place over a time period, would
require lengthy observations, but questions can be answered
in few seconds.
Ex: no. of trip to the supermarket in a week
4. It is not normally feasible to observe personal activities.
◦Ex- brushing teeth.
DR. AMITABH MISHRA 10
1.Unwillingness of respondents to provide information.
1.Questions about income or about personal subjects frequently meet
refusal.
2.Inability of respondents to provide information.
1.Many motivations are largely subconscious.
2.Most products are brought without any conscious array of reasons for
and against.
Ex- How many consumers analyze their reason for buying a particular
bar of soap?
DR. AMITABH MISHRA 11
3.Respondents can not furnish information
because they are unable to remember it
Ex- How many times did you eat corn flakes for breakfast
last months. (only those who always or never eat cornflakes
could answer such questions accurately)
4.The questioning process influence the result
obtained
Ex- “Don’t you see any problem with using credit cards for
online purchases?”
5.Often respondents attempts to give answer
that they will think please the interviewer

“In Non Disguised questioning questionnaire are constructed
in such a way that the objective is clear to the respondent”.
In Disguised questioning questionnaire are constructed in
such a way that the objective is not clear to the respondent”.
DR. AMITABH MISHRA 16
In Marketing research most of questionnaire study are
structured and non disguised study.
Data obtained in structured and non disguised study are
easier to tabulate and interpret than data gathered in other
ways.

3:- Did you buy it or it was a gift?
buy Gift
4:- Which member of your family, if any, can now
play piano?
DR. AMITABH MISHRA 18
In this technique, instead of approaching respondents with
a fixed list of questions. The interviewer attempts to get
respondents to talk freely about subject of interest.
Such interviews do not involve the formal
questionnaires, yet the discussion is directed to the
specific problem at hand.
DR. AMITABH MISHRA 19
Direct questioning dealing with motives rarely
elicit useful answers.
Most people do not have clear idea why they make
specific marketing decision.
Few examples of non structured and non
disguised questioning are-
1.Depth Interview.
2.Focus-group Interview.
DR. AMITABH MISHRA 20
Focus-group
Interview
DR. AMITABH MISHRA 21
The focus group interview is a panel of people, led
by a trained moderator, who meet for 90 min to 2
hrs. The moderator uses the principle of group
dynamics to focus or guide the group in an
exchange of ideas, feelings and experience on
specific topic.
The moderator’s task is to ensure that open
discussion is “focused” on some area of interest.
DR. AMITABH MISHRA 22
Focus groups are used to generate ideas, to learn
the respondents’ “vocabulary,” and to gain some
insights into basic needs and attitudes.
Focus group interviews may be-
1.Traditional
2.Non Traditional or Online
DR. AMITABH MISHRA 23
DR. AMITABH MISHRA 24
Group Size 8-12
Group Composition Homogeneous, respondents,
prescreened
Physical Setting Relaxed, informal atmosphere
Time Duration 1-3 hours
Recording Use of audiocassettes and
videotapes
Moderator Observational, interpersonal, and
communication skills of the
moderator
1.Traditional: Select 6 to 12 persons and meet in a dedicated room
with one-way mirror for client viewing, for about two hours.
2.Nontraditional: Online focus groups are a form of nontraditional
focus groups. Online focus group is one in which the respondents
and/or clients communicate and/or observe by use of the
Internet.
◦ Online with client viewing from distant locations.
◦ May have 25 or even 50 respondents.
◦ Allow client interaction.
◦ May take place in nontraditional locations.

Depth
Interviews
“Depth interview is an unstructured, direct, personal
interview in which a single respondent is probed by a
highly skilled interviewer to uncover underlying
motivations, beliefs, attitude and feeling on a topic”
Depth interview is a set of probing questions posed
one-on-one to a subject by a trained interviewer so
as to gain an idea of what the subject thinks about
something or why he or she behaves a certain way.
DR. AMITABH MISHRA 32
A depth interview can take from 30 min to 1 hr.
Unlike focus group interview, depth interview are
conducted on a one to one basis.
Like focus group interview, depth interview are
unstructured and direct way of obtaining
information.

Many people are either unwilling or unable to accurate reports as
to their own attitudes and motivations.
In such situations other methods probably give bias results.
To over come this difficulty psychologists have developed non
structured and disguised techniques known as-
◦Projective Techniques.
DR. AMITABH MISHRA 36
DR. AMITABH MISHRA 37
“An unstructured, indirect form of questioning that
encourages respondents to project their underlying
motivations, beliefs, attitudes or feelings regarding
the issues of concern”.
In projective techniques all individuals, in
describing a situation, interpret that situation to a
degree.
The description they give is a mixture of their own
attitude, belief, feeling and motivation.
DR. AMITABH MISHRA 38
In projective techniques, respondents are asked to interpret
the behavior of others.
In interpreting the behavior of others, respondents indirectly
project their own motivations, beliefs, attitudes, or feelings
into the situation.

In association technique, an individual is presented
with a stimulus and asked to respond with the first
thing that comes to mind.
Word association is best known Projective
Technique.
DR. AMITABH MISHRA 41
In Word association, a series of word is read one at a time to
respondents. After each word the respondent say the first thing that
come in to their mind.
The words of interest, called test words, are interspersed throughout the
list which also contains some neutral, or filler words to disguise the
purpose of the study.
DR. AMITABH MISHRA 42
Responses are analyzed by calculating:
◦ The frequency with which any word is given as a response;
◦ The amount of time that elapses before a response is given
and
◦ The number of respondents who do not respond at all to a
test word within a reasonable period of time.
DR. AMITABH MISHRA 43
Say the first thing that come in to their mind
regarding Big Bazar’s
◦Location
◦Parking
◦Shopping
◦Quality
◦Price.
DR. AMITABH MISHRA 44
“In completion technique the respondent is asked to complete an
incomplete stimulus situation”.
Completion techniques can be classified as-
1. Sentence completion.
2. Story completion.
DR. AMITABH MISHRA 45
DR. AMITABH MISHRA 46
Sentence completion
In sentence completion, respondents are given an
incomplete sentences and asked to complete them.
Generally, they are asked to use the first word or
phrase that comes to mind.
In Sentence Completion respondents are required to
complete a partial sentence.
DR. AMITABH MISHRA 47
Complete this sentence:
1. A person who shops at Spencer is _____ ____ __ __ __ _
2. Cadbury’s “Dairy Milk Silk” is most liked by _____ ____ _
3. When I think of spending my summers on Hill Station, I… …
… ………………………
4. “People who buy over internet are………………………… … … …
A variation of sentence completion is paragraph completion,
in which the respondent completes a paragraph beginning with
the stimulus phrase.
DR. AMITABH MISHRA 48
DR. AMITABH MISHRA 49
DR. AMITABH MISHRA 50
Story Completion
In story completion, respondents are given part of a
story – enough to direct attention to a particular
topic but not to hint at the ending. They are
required to give the conclusion in their own words.

DR. AMITABH MISHRA 52
With a picture response, the respondents are asked to
describe a series of pictures of ordinary as well as
unusual events. The respondent's interpretation of
the pictures gives indications of that individual's
personality.

EXAMPLE
In cartoon tests, cartoon characters are shown in a
specific situation related to the problem. The
respondents are asked to indicate what one
cartoon character might say in response to the
comments of another character. Cartoon tests are
simpler to administer and analyze than picture
response techniques.

THIERD
PERSON TECH.
DR. AMITABH MISHRA 57
Role playing. Respondents are asked to play the role or
assume the behavior of someone else.
Third-person technique. The respondent is presented
with a verbal or visual situation and the respondent is
asked to relate the beliefs and attitudes of a third person
rather than directly expressing personal beliefs and
attitudes. This third person may be a friend, neighbor,
colleague, or a “typical” person.
DR. AMITABH MISHRA 58
They may elicit responses that subjects would be
unwilling or unable to give if they knew the purpose of
the study.
Helpful when the issues to be addressed are personal,
sensitive, or subject to strong social norms.
Helpful when underlying motivations, beliefs, and
attitudes are operating at a subconscious level.
DR. AMITABH MISHRA 59
Suffer from many of the disadvantages of unstructured
direct techniques, but to a greater extent.
Require highly-trained interviewers.
Skilled interpreters are also required to analyze the
responses.
There is a serious risk of interpretation bias.
They tend to be expensive.
May require respondents to engage in unusual behavior.

questions.
The interviewer uses a paper questionnaire and
records the responses with a pencil.
DR. AMITABH MISHRA 66
A survey that uses fax machines as a way for respondents
to receive and return questionnaires.
The researcher generally makes a phone call intimating
the respondents about the survey matter and then send the
questionnaire to the respondents by a fax machine
DR. AMITABH MISHRA 67
◦Fax survey reduces sender’s printing and postage costs
◦Fax survey is quicker than traditional mail surveys
◦In Fax surveys, Only respondents with fax machines who
are willing to exert the extra effort will return
questionnaires.
◦Fax survey is not suitable for household survey as the fax
machines are rarely found in houses.
DR. AMITABH MISHRA 68
Voice mail survey is completely automated telephone survey method
where fixed response questions are posed to respondents through a
pre recorded voice of the professional interviewer and the
respondent is supposed to press the telephone button to register
the responses.
The process is completely mechanical and lack the personal touch of
the interviewer.
DR. AMITABH MISHRA 69
In CATI the telephone interviewer has a personal computer ,
that is networked with the phone system and to a central data
processing unit.
