  1. Types Of Research • Exploratory • Descriptive • Causal

  2. Uncertainty Influences The Type Of Research CAUSAL OR DESCRIPTIVE EXPLORATORY COMPLETELY CERTAIN ABSOLUTE AMBIGUITY

  3. Information • Reduces uncertainty • Helps focus decision making

  4. Degree of Problem Definition Exploratory Research Descriptive Research Causal Research (Unaware of Problem) (Aware of Problem) (Problem Clearly Defined) “Our sales are declining and “What kind of people are buying “Will buyers purchase more of we don’t know why.” our product? Who buys our our products in a new package? competitor’s product?” “Would people be interested “Which of two advertising in our new product idea?” “What features do buyers prefer campaigns is more effective?” in our product?” possible situation

  5. Exploratory Research Secondary data Experience survey Pilot studies

  6. Exploratory Research • Initial research conducted to clarify and define the nature of a problem • Does not provide conclusive evidence • Subsequent research expected

  7. Descriptive Research • Describes characteristics of a population or phenomenon • Some understanding of the nature of the problem

  8. I keep six honest serving men, (they taught me all I knew), their names are and when, and how, and why, what, and where and who.” --Rudyard Kipling

  9. Descriptive Research Example • Weight Watchers average customer • Woman about 40 years old • Household income of about $50,000 • At least some college education • Trying to juggle children and a job

  10. Descriptive Research Example • Men’s fragrance market • 1/3 size of women’s fragrance market • But growing at a faster pace • Women buy 80 % of men’s fragrances

  11. Causal Research • Conducted to identify cause and effect relationships

  12. Identifying Causality • A causal relationship is impossible to prove. • Evidence of causality: • 1. The appropriate causal order of events • 2. Concomitant variation--two phenomena vary together • 3. An absence of alternative plausible explanations

  13. Stages of the Research Process Discovery and Definition Problem Discovery and Definition and so on Research Design Conclusions and Report Sampling Data Processing and Analysis Data Gathering

  14. Research Stages • Cyclical process - conclusions generate new ideas • Stages can overlap chronologically • Stages are functionally interrelated • Forward linkages • Backward linkages

  15. Selection of exploratory research technique Problem discovery Problem Discovery and Definition Sampling Selection of exploratory research technique Probability Nonprobability Secondary (historical) data Experience survey Pilot study Case study Collection of data (fieldwork) Data Gathering Data Processing and Analysis Editing and coding data Problem definition (statement of research objectives) Data processing Selection of basic research method Research Design Conclusions and Report Interpretation of findings Experiment Survey Observation Secondary Data Study Report Laboratory Field Interview Questionnaire

  16. Stages In The Research Process • Problem Discovery and Problem Definition • Research Design • Sampling • Data Gathering • Data Processing and Analysis • Conclusions And Report

  17. Problem Discovery And Definition • First step • Problem, opportunity, or monitor operations • Discovery before definition • Problem means management problem

  18. “The formulation of the problem is often more essential than its solution” Albert Einstein

  19. State the research questions and research objectives

  20. If you do not know where you are going,any road will take you there.

  21. Experience Survey Case Study Pilot Study Secondary (historical) Data Exploratory Research

  22. Exploratory Research Techniques Two Examples • Secondary data (historical data) • Previously collected • Census of population • Literature survey • Pilot study • A number of diverse techniques

  23. Focus Group Interview

  24. Research Design • Master plan • Framework for action • Specifies methods and procedures

  25. Basic Research Methods • Surveys • Experiments • Secondary data • Observation

  26. Selecting a Sample Sample: subset of a larger population. SAMPLE POPULATION

  27. Sampling • Who is to be sampled? • How large a sample? • How will sample units be selected?

  28. Data Gathering Stage

  29. Data Processing and Analysis

  30. Conclusions And Report Writing • Effective communication of the research findings

  31. Research Proposal • A written statement of the research design that includes a statement explaining the purpose of the study. • Detailed outline of procedures associated with a particular methodology

  32. Analysis of the Situation Problem Definition Statement of Research Objectives Defining Problem Results in Clear Cut Research Objectives Symptom Detection Exploratory Research (Optional)
