  2. The Marketing Research Process Figure 1.4 The Marketing Research Process Step 1: Defining the Problem Step 2: Developing an Approach to the Problem Step 3: Formulating a Research Design Step 4: Doing Field Work or Collecting Data Step 5: Preparing and Analyzing Data Step 6: Preparing and Presenting the Report

  3. Research Design • A master plan that specifies the methods and procedures for collecting and analyzing needed information.

  4. Figure 3.8 Tasks Involved in a Research Design Tasks Involved In a Research Design Define the Information Needed Design the Exploratory, Descriptive, and/or Causal Phases of the Research Today’s Topic Specify the Measurement and Scaling Procedures Construct a Questionnaire Specify the Sampling Process and the Sample Size Develop a Plan of Data Analysis

  7. Exploratory Research • Usually conducted during the initial stage of the research process • Purposes • To narrow the scope of the research topic, and • To transform ambiguous problems into well-defined ones

  8. Exploratory Research Techniques • Secondary Data Analysis • Secondary data are data previously collected & assembled for some project other than the one at hand • Pilot Studies • A collective term for any small-scale exploratory research technique that uses sampling but does not apply rigorous standards • Includes • Focus Group Interviews • Unstructured, free-flowing interview with a small group of people • Projective Techniques • Indirect means of questioning that enables a respondent to project beliefs and feelings onto a third party or an inanimate object • Word association tests, sentence completion tests, role playing

  9. Exploratory Research Techniques • Case Studies • Intensively investigate one or a few situations similar to the problem situation • Experience Surveys • Individuals who are knowledge about a particular research problem are questioned

  10. Conclusive Research • Provide specific information that aids the decision maker in evaluating alternative courses of action • Sound statistical methods & formal research methodologies are used to increase the reliability of the information • Data sought tends to be specific & decisive • Also more structured & formal than exploratory data

  11. Types of Conclusive Research • Descriptive Research • Describes attitudes, perceptions, characteristics, activities and situations. • Examines who, what, when, where, why, & how questions • Causal Research • Provides evidence that a cause-and-effect relationship exists or does not exist. • Premise is that something (and independent variable) directly influences the behavior of something else (the dependent variable).

  12. Common Characteristics of Descriptive Studies • Build on previous information • Show relationships between variables • Representative samples required • Structured research plans • Require substantial resources • Conclusive findings

  13. Figure 3.5 Major Types of Descriptive Studies Consumer Perception And Behavior Studies • Image • Product Usage • Advertising • Pricing Market Characteristic Studies • Distribution • Competitive Analysis Sales Studies • Market Potential • Market Share • Sales Analysis Major Types of Descriptive Studies Descriptive Studies

  17. Common Characteristics of Causal Studies • Logical Time Sequence • For causality to exist, the cause must either precede or occur simultaneously with the effect • Concomitant Variation • Extent to which the cause and effect vary together as hypothesized • Control for Other Possible Causal Factors

  18. How Descriptive & Causal Designs Differ • Relationship between the variables • Descriptive designs determine degree of association • Causal designs infer whether one or more variables influence another variable • Degree of environmental control • Descriptive designs enjoy lesser degrees of control • Order of the variables • In descriptive designs, variables are not logically ordered

  19. Comparison of Research Designs

  20. Basic Research Methods • Secondary Data Analysis • Historical analysis • Surveys • Asking; self-reported • Experiments • Testing in controlled environments • Observation • Watching & recording

  21. Which is the “Best” Research Design & Method? • “You cannot put the same shoe on every foot.” • Publilius Syrus • It depends on the • problem of interest, • level of information needed, • resources, • researcher’s experience, etc.
