Title: Seven Steps of Marketing Research
1Surveys
2What is a Survey?
3Why Survey?
- Get lots of structured information from lots of
people. - Simplify and standardize data collection.
- Use statistics to make predictions.
- Find out about things that can not be observed.
Such as Thoughts, Emotions, Opinions, Intentions,
Attitudes
4- why people do or do not do something.
- Likes, dislikes, attitudes, behaviors, influences
- the process consumers go through before taking
some action. - Decision making process
- Information on age, income, occupation, marital
status, stage in the family life cycle,
education, and other lifestyle factors is
necessary to the identification and definition of
market segments.
5Survey Methods

- Door-to-Door (in-home), Mall-Intercept,
Purchase-Intercept, Executive (office) - Telephone-Interview
- People Computer assisted (CATI)
- Self-Administered
- Mail Survey
- Fax
- One-time vs. Panels
- Computer
- Direct Computer Interviewing
- Interactive voice response technology-Automated
Telephone - Surveys

7Personal Interviews
8Personal Interviews
Advantages
- Can arouse and keep interest
- Can build rapport and enlist cooperation
- Ask complex questions
- Immediate feedback
- Can use visual and other aids
- Clarify misunderstandings
- High degree of flexibility
- Probe for more complete answers
- Do not need an explicit or current list of
households or individuals
9Personal Interviews
Disadvantages
- Bias of Interviewer
- Response Bias
- Embarrassing/personal questions
- Time Requirements
- Cost Per Completed Interview Is High.
- High refusal rate
- A trained staff of interviewers that is
geographically near the sample is needed. - The total data collection period is likely to be
longer than for most procedures. - High selection error non-representative sample
10Telephone Interviewing
What are the Important Aspects of Telephone
Interviewing?
-
- Selecting telephone numbers
- Pre specified list
- A directory
- Random dialing procedure
- Random digit dialing
- Systematic random digit dialing (SRDD)
- The introduction
- When to call
- Call reports
11(No Transcript)
12Telephone Interviewing
Advantages
- Central location, under supervision, at own hours
- More interviews can be conducted in a given time
- Travelling time is saved
- More hours of the day are productive
- Repeated call backs at lower cost
- Lower administrative costs/ Lower cost per
completed interview - Less sample bias
- Better access to certain populations
- Shorter data collection periods.
13Telephone Interviewing
Limitations and Disadvantages
- Inability to employ visual aids or complex tasks
- Can't be longer than 5-10 min. or they get boring
- Amount of data that can be collected is
relatively less - A capable interviewer essential
- Sample bias -- Not all people have phones, or are
not listed - Nonresponse associated with RDD sampling is
higher than with interviews - Possibly less appropriate for personal or
sensitive questions if no prior contact - National Do Not Call List 1-866-580-DNCL
(866-580-3625) - http//www.LNNTE-DNCL.gc.ca
14Increasing Phone Survey Response
- Call at a convenient time (Weekdays 7-9 PM,
Sunday afternoon) - Have a nice Pleasant introduction
- Emphasize you are not selling anything.
- State how long it will take.
- Keep the survey short
15Self-Administered Types of Survey Research
Direct Mail Survey Questionnaire is distributed
to and returned from respondents via the postal
service.
Respondent Reads Survey Questions and Records
Answers Without Assistance
Mail Panel Survey Selected group of individuals
that have made an advance agreement to
participate in a series of direct mail surveys.
Drop Off Survey Questionnaires are left with
respondent to be completed at a later time and
returned to the researcher.
16- Mail Surveys
- Requires a broad identification of the
individuals to be sampled before data collection
begins - Ad Hoc Mail Surveys (cold)
- Questionnaires for a particular project sent to
selected names and addresses with no prior
contact by the researcher. - Mail Panels (warm)
- Pre-contacted and screened participants who are
periodically sent questionnaires. - A mail panel is a type of longitudinal study. A
longitudinal study in one in which the same
respondents are re-sampled over time.
17Mail Surveys
Some Decisions That Need to Be Taken
- Type of Return Envelope
- Postage
- Method of Addressing
- Cover Letter
- The Questionnaire Length, Layout, Color, Format
Etc - Method of Notification
- Incentive to Be Given
18Mail Surveys
Advantages
- Relatively low cost
- Reliable answers as no inhibiting intermediary
- Survey answered at respondents discretion
- Can be accomplished with minimal staff and
facilities. - Provides access to widely dispersed samples.
- Respondents have time to give thoughtful answers,
look up records, or consult others.
19Mail Surveys
Disadvantages
- No control over whom the respondent consults
before answering the questions - The identity of the respondent is inadequately
controlled - The speed of the response can't be monitored
- No control on the order in which the questions
are exposed or answered - Open questions usually are not useful.
- Good reading and writing skills are needed by
respondents. - The interviewer is not present to exercise
quality control with respect to answering all
questions, meeting questions objectives, or the
quality of answers provided. - High non-response rate
20Mail Surveys
Disadvantages (Contd.)
- The respondent may not clearly understand the
question and no opportunity to clarify - No long questionnaires
- Need for good up-to date mailing list
- Response rate is generally poor
- Number of problems such as obsolescence,
omissions, duplications, etc - Ineffective as a way of enlisting cooperation.
21Factors Affecting the Response Rate
- Perceived amount of work required, and the length
of the questionnaire - Intrinsic interest in the topic
- Characteristics of the sample
- Credibility of the sponsoring organization
- Level of induced motivation
22Tactics Employed to Increase Mail Survey Response
Rate
- Advance postcard or telephone call alerting
respondent of survey. - Follow-up postcard or phone call.
- Monetary incentives (how much?).
- Premiums (pencil, pen, keychain, coupons, etc.).
- Postage stamps rather than metered envelopes.
- Self-addressed, stamped return envelope.
- Personalized address and well-written cover
letter. - Personally signed cover letter.
23Tactics Employed to Increase Mail Survey Response
Rate
- Entry into drawing for prize.
- Emotional appeals.
- Affiliation with institutions or reputed
organizations. - Multiple mailings of the questionnaire.
- Bids for sympathy.
- Offer to share information from the survey.
- Promise of contributions to favorite charity.
24Drop-off questionnaires
- The interviewer can explain the study, answer
questions, and designate a respondent. - Response rates tend to be like those of personal
interview studies. - There is more opportunity to give thoughtful
answers and consult records. - Costs about as much as personal interviews.
- A field staff is required.
25Fax Surveys
Advantages
- Relatively low cost
- Can be accomplished with minimal staff and
facilities - Provides access to widely dispersed samples.
- Respondents have time to give thoughtful answers.
- Local faxes are free.
- Administrative costs are fixed.
- It is fast.
- List management is easy.
- Can send and receive by computer.
26Fax Surveys
Disadvantages
- Higher fixed costs for computer/fax equipment,
multiple phone lines. - Cost varies by time on line, time of day,
distance, and telephone carrier. - Generally limited to organizational populations.
- Loss of anonymity.
27Internet Surveys
To realize the importance of the marketing
research interviewer.
- Internet Samples
- Unrestricted
- Open to any Internet user.
- Screened
- adjust for unrepresentitiveness of the
self-selected respondents by imposing quotas
based on some desired sample characteristics
- Recruited
- to target populations in surveys that require
more control of the sample
28Internet Surveys
Advantages
- The advantages of interviewer administration (In
contrast to mail surveys). - smaller staff needed,
- High-speed,
- Instantaneous data access real time reporting
- Cost efficient
- Automatic data entry
- Multimedia stimuli
- Easy to update
- Ability to reach a lot of people, and often those
hard to reach
29Internet Surveys
Advantages
- Potential for longitudinal studies
- Surveys can be unobtrusively included with a
general site - pre-screening of respondents possible
- tracking
- Easy to personalize
- No geographic boundaries
- supervision and quality control potentially
better. - better response rate from a list sample than
from mail - use a branching or skip pattern
30Internet Surveys
Disadvantages
- Internet users are not representative of the
population as a whole (strong sample bias) - Strong selection bias for respondents who are not
pre-screened - security/privacy issues
- unrestricted anyone can complete the
questionnaire - fully self-selecting
31- Free Trial Survey Software
- Free Online Surveys
- eSurveypro
- Question Pro
- Keysurvey
- Checkbox survey
32E-mail Questionnaires
- The questionnaire is prepared like a simple
E-mail message, and is sent to a list of known
E-mail addresses. The respondent fills in the
answers, and E-mails the form plus replies back
to the research organization
33Increasing Response Internet/E-mail Survey
- Almost all the actions listed for mail survey
should hold for E-Mail/Internet survey with some
modifications. - The questionnaire should be fairly short.
- No need for advance notification
- Have short, pleasant introduction
- Monetary incentives not given. But sharing
information would be nice. - Reminder e-mail would be useful.
34Criteria for Determining Choice Of Particular
Survey Methods
- Sample Criteria Ability to reach and get
responses from the desired sample (sample
control) - right type of people
- adequate sample size.
- Information Criteria Ability to get the desired
information from respondents. - Need to Expose Respondents to Various Stimuli or
Perform Certain Specialized Tasks e.g. Taste
tests, product concept and prototype tests, etc. - Length of Questionnaire
- Degree of Structure of the Questionnaire
- Control social desirability
- Administrative Criteria
- time for data collection and analysis
- Interviewer control
- Error control
- Budget
35Factors Determining the Choice of Survey Method.
- Personal
- Mail
- Phone
- E-Mail/Internet.
Use for long, complex questionnaires where
respondent is important and budgets are
high. Use when you have a mailing list, somewhat
long / complex questionnaire, and budgets are
low. Use to reach a large number of people
quickly and you have a short questionnaire that
can be easily understood. Use when target
audience is educated, topic interesting, short
questionnaire, have e-mail list,
representativeness not a major issue

Special features Visual materials may be shown or demonstrated extended probing possible Respondents may answer questions at own convenience has time to reflect on answers Field and supervision of data collection are simplified quite adaptable to computer technology Data collection automatic Skip patterns automatic
Note These reflect typical situations. For
example, an elaborate mail survey may be far
more expensive than a short interview, but this
is generally not the case.
40Potential Problems with Surveys
How accurate are the results?
- Did you ask the right questions in the right way?
- Did you ask the right people?
- Did they tell you the truth, the whole truth, and
nothing but the truth? - Will they?
- Can they? Do they have the knowledge, opinions,
attitudes, or facts required. Do they understand
the questions? - Structure causes a loss of data richness.
- Have the Respondents/Interviewers understood and
correctly recorded the responses - Lack of control causes time and response problems.
41Overview of the Types of Errors in Survey
Research Methods
- Survey research errors can be classified as
either
- Random Sampling Error
- statistically measured difference between the
actual sampled results and the estimated true
population results. - error because of chance variation
- Reduce by increasing sample size
- Range can be estimated with a certain level of
confidence
- Nonsampling Error (Systematic Error)
- results from mistakes or problems in the research
design or its execution - Causes data to be misleading or incomplete in
some systematic way from true population
parameter - If you are aware of the problem you may be able
to deal with it.
42Systematic Sample Design Error
- Frame Error The list from which you draw your
sample is not what you think it issome on it
dont belong and/or some who belong are not on it
sample is not representative of population
(e.g. telephone directory) - Population Specification Error incorrect
definition of the universe or population from
which the sample is to be selected. You left
people out of the study. - Selection Error You include or exclude people
in the sample so that it is not random. Use of
incomplete or improper sampling procedures or
when appropriate selection procedures are not
properly followed (e.g. non-probability samples
such as intercept surveys)
43Systematic Measurement Error
- Difference between the information sought and
that obtained
- Surrogate Information Error
- Acquisition of the wrong data because wrong
question was asked. failure to define problem,
e.g. New Coke - Interviewer Error
- interviewer may, consciously or unconsciously,
influence respondents to give untrue or
inaccurate answers. training problem - Instrument Bias
- misunderstood or leading questions
questionnaire design - Processing Error
- sloppy data input
- Non-response Bias
- differences between the did vs. did not
answer question - Response Bias
- a failure to tell the truth, consciously or
unconsciously
44Your company has just launched a new brand of
pancake syrup. In order to improve sales the
marketing department would like to know why
consumers buy the brands and sizes they do. How
would you go about collecting this information?
45Calgary Transit would like to conduct a ridership
survey. Funds are limited but they need a
relatively large sample. How would you suggest
they gather the information?
46Your company makes the new flip and fold device.
You want to find out what consumers think about
it and how much they are willing to pay. What
sort of survey technique do you use and why. Who
do you target in your survey
47OBSERVATIONAL RESEARCH
Watching what people do
- The information must be observable
- Helpful if the behavior is repetitive and of
short duration - Approaches to observational research
- Natural Versus Contrived Situations
- Open Versus Disguised Observation
- Structured Versus Unstructured
- Human Versus Machine Observers
48What does gathering data through Observation
entail
What are the advantages of observational data
collection as opposed to surveys?
What are the relative disadvantages of
observational data collection as opposed to
surveys?
49- Main Observational Research Methods
- Direct Observation
- Shopper Patterns and Behavior
- Contrived Observation
- Mystery Shopper
- Content Analysis
- Analyzing written material into meaningful units,
using carefully applied rules - Physical Trace Measures
- Garbology
- Ethnographic Research
- The researcher becomes Immersed in or part of the
group - Behavior (Emotion) Recording Devices
50- Toothpaste manufactures have found consistently
that if they ask for detailed information on the
frequency with which people brush their teeth,
and then make minimal assumptions as to the
quantity of toothpaste used on each occasion, as
well as spillage and failure to squeeze the tube
empty, the result is a serious overstatement of
toothpaste consumption. - How would you explain this phenomenon?
- Would it be possible to design a study to
overcome these problems and obtain more accurate
estimates of consumption?
51Advantages
- We see what people actually do
- May avoid interviewer bias
Disadvantages
- No information on motives attitudes or intentions
- Time-consuming and expensive
52- Traffic Counters
- Time and flow in retail stores
- Behavior Measurement
- People Reader reading habits
- Physiological Measurement
- EEG electroencephalogram
- GSR galvanic skin response
- Pupilometer pupil dilation
- Scanner Based
- Store scanners read the UPC codes on products and
produce instantaneous information on sales
