                  Information Sought
   Guided by research problem
   Determine first if secondary information is
    available
       (i.e, is survey needed?)

   Determine if respondents can answer the key
    questions
   Avoid straying off into “interesting” areas of
    questioning

    Quality of Measurement

   Reliability:
       Are the measures consistent?
       Are they free of random error?


   Validity:
       Are we really measuring what we think we are
        measuring?

         *For a measure to be valid, it must be reliable.

                                         25
             Guidelines for Sequencing
   Use simple, interesting opening questions to
         build momentum
   Use the funnel approach, asking broad questions
         first
   If multiple filter questions are necessary, try to ask
    them before asking more detailed questions.
       e.g., “have you patronized a fast food restaurant in the past two
        weeks?”
                                                                            26
        Guidelines for Sequencing
   Group questions by topic or form


   When switching topics, use transitional phrases
    to make it easier for respondents to switch their
    for trains of thought.


   Place demographics, as well as difficult or
    sensitive questions, at the end                27
            Context Effects
   Whether ask “How do you feel today?” at
    beginning

   Whether ask about something positive or
    negative

                                                              29
            Example of            Order Effects
   Survey about brand confusion between two companies
       Muffler King and Speedy Muffler King
       Legal case about confusion due to entry of
         Speedy Muffler King to market already occupied by
         Muffler King


   Respondents more apt to show signs of confusion when
    SMK questions preceded questions about MK than vice
    versa.
       When first asked about MK, they were alerted that Speedy
         Muffler King was not a “fast Muffler King” but a different firm
       No alert (and thus confusion) when first asked about Speedy …
                                                                      30
               Effect of Prior Mention of
                Sensitive Issue Before
                  Rating of the Brand
   Two standard poll questions.
     1. whether people thought the country was headed in the right
        direction or was "seriously off on the wrong track.“
     2. whether those interviewed approved or disapproved of the job
        George W. Bush was doing as president.

   To measure the "Bush effect," the interviewers varied the order of the
    questions.
        Half of the respondents were first asked what they thought about Bush's
         performance. Then they were asked about the direction of the country.
        For the other half, the order was reversed.

   Asking first about Bush boosted the proportion that saw the country
    headed “in the right direction” by 8 percentage points -- from 34
    percent to 42 percent.                                             31
   Bush's magic didn't hold in the other direction, however.
        His job approval rating fell by about 6 percentage points (to 60 percent)
         when people were first asked where they thought the country was
         headed.


   Larry Hugick, vice president of Princeton Survey Research
    Associates: "People's opinions about the president and the direction
    of the country are intertwined,"
        "If the Bush approval question is first, people tend to respond in the
         context of their views of Bush and therefore express more positive views
         about where the country is headed.
        If the direction of country question is first, dissatisfaction with the country
         tends to depress Bush’s ratings.“
             (negative prime  more negative ratings)
                                                                                    32
   But Bush isn't the equal of the master presidential prestidigitator, Bill
    Clinton -- at least not yet.
        When The Post conducted a similar test of Clinton's mood-swaying
         prowess in 1998, asking the job approval question first was enough to
         boost the right direction number by 10 percentage points.


   But unlike what happened with the Bush test, asking the right direction
    first didn't move the Clinton job approval rating one bit
       suggesting that public views of Clinton in his sixth year in the White

         House were more firmly fixed than current opinions of Bush.

      MULTI-ATTRIBUTE ATTITUDE MODEL

                       Aj =  (wi) (bij)

Aj    = Attitude toward Brand j (a product or service)
wi    = the goodness/importance of the attribute
bij   = belief about brand j on attribute i
      = summation over n attributes

Alternative formulation is the Ideal Point Model:
    Aj =  (wi) (bij - Ij), where I = ideal point or ideal level of Attribute I
Can alter equation further to deal with attributes where more is not better
  (I.e., sweetness, weight)

                                                                            43

   From brand inventory, assess what types of
    incremental or updated information (e.g.,
    awareness, perceptions) is needed most
       Have to prioritize
       Cover as much as possible
       But fewer high quality questions are better than many
        low quality ones

              More about Your Research
   Probable questionnaire types
       Personal administration of written questionnaire
       Personal interviews (esp. for qualitative q’s)
       Internet or phone


   Might try to consider differences between:
       users,
       rejecters / defectors, and
       non-users


   I will be your consultant                              55
    Some Concluding Comments about
       Your Quantitative Research
   Use mostly scaled measures for quantitative surveys
       instead open-ends (hard and time cost to code)
   All measures should be relative to the competition
   Measures should capture the components of brand
    equity and the hierarchy of effects
       (Integrated Marketing Communications)


   Pretest, pretest, pretest!
                                                         56
        Why Pretest Questionnaires?
   Test for:
       Length of time
       Does it measure what you want?
            Ask both the client and the respondents
       Anything missing that should be asked?
       Clarity
            Unambiguous questions
            Unambiguous answers
                                                       57
               Why Pretest?             (cont’d)


   Test to learn:
       Variability of answers
            (Use to calculate needed sample size)


       Ease of answers


       Whether interviewers perform as trained?


                                                     58
                   How to Pretest
   Informal
       colleagues
       secretaries and other staff
       family
       convenience samples


   Pilot test
       individual interviews
       focus groups
                                      59
               How to Pretest (cont’d)
   Debriefing pretest
       interview respondents after they have completed
        questionnaire


   Protocol pretest
       ask respondents to think out loud as they fill out
        questionnaire


   Revise and pretest again (and again if necessary);
       pretest until added pretests learn nothing new

                 An Alternative View about
            How to Measure Importance Weights:

VII. Problem Detection Analysis
1. Importance weights often miss things that seem at face
   value to be important

2. Instead of focusing on consumers’ perceptions of
   importance, this focuses on problems

 Problem Detection Analysis                       (Cont’d)



First Step:
a. Use focus groups and/or depth interviews

b. Ask about what irritates, frustrates, etc. when using
  the product

c. Accumulate a list of (50 150) problems




                                                       70
              Problem Detection Analysis:
          Second Step: Survey at least 200
            prospects about each problem and ask:


a. How often does it occur?   (Frequency)

b. How much does it irritate you when it
     occurs?            (Bothersomeness)

c. In your opinion, which of these items are already
   being used as advertising or product claims
  (Preemptibility)
