  1. Research Problem Definition Assistant Professor Dr. Chanin Yoopetch

  2. 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

  3. Uncertainty Influences the Type of Research CAUSAL OR DESCRIPTIVE EXPLORATORY COMPLETELY CERTAIN ABSOLUTE AMBIGUITY

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

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

  6. Problem Definition • The indication of a specific business decision area that will be clarified by answering some research questions.

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

  8. Ascertain the decision maker’s objectives Determine unit of analysis Understand background of the problem Determine relevant variables Isolate/identify the problem, not the symptoms State research questions and objectives The Process of Problem Definition

  9. Ascertain the Decision Maker’s Objectives • Decision makers’ objectives • Managerial goals expressed in measurable terms.

  10. The Iceberg Principle • The principle indicating that the dangerous part of many business problems is neither visible to nor understood by managers.

  11. Understand the Background of the Problem • Exercising judgment • Situation analysis - The informal gathering of background information to familiarize researchers or managers with the decision area.

  12. Isolate and Identify the Problems, Not the Symptoms • Symptoms can be confusing

  13. Symptoms Can Be Confusing Twenty-year-old neighborhood swimming association: • Membership has been declining for years. • New water park -residents prefer the expensive water park???? • Demographic changes: Children have grown up

  14. Problem Definition Organization Symptoms Based on Symptom True Problem Twenty-year-old neighborhood swimming association in a major city. Membership has been declining for years. New water park with wave pool and water slides moved into town a few years ago. Neighborhood residents prefer the expensive water park and have negative image of swimming pool. Demographic changes: Children in this 20-year-old neighborhood have grown up. Older residents no longer swim anywhere.

  15. Determine the Unit of Analysis • Individuals, households, organizations, etc. • In many studies, the family rather than the individual is the appropriate unit of analysis.

  16. Determine the Relevant Variable • Anything that may assume different numerical values

  17. Types of Variables • Categorical • Continuous • Dependent • Independent

  18. Hypothesis • An unproven proposition • A possible solution to a problem • Guess

  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. Broad research objectives Statement of business problem Exploratory research (optional) Specific Objective 1 Specific Objective 2 Specific Objective 3 Research Design Results Statement of business problem

  22. Ascertain the decision maker’s objectives Determine unit of analysis Understand background of the problem Determine relevant variables Isolate/identify the problem, not the symptoms State research questions and objectives The Process of Problem Definition

  23. Theory Building and Observation Methods

  24. Theories Theories are nets cast to catch what we call “the world”: to rationalize, to explain, and to master it. We endeavor to make the mesh ever finer and finer. Karl R. Popper

  25. Two Purposes Of Theory • Prediction • Understanding

  26. Theory • A coherent set of general propositions used as principles of explanation of the apparent relationships of certain observed phenomena.

  27. Concept (or Construct) • A generalized idea about a class of objects, attributes, occurrences, or processes that has been given a name • Building blocks that abstract reality • “leadership,” “productivity,” and “morale” • “gross national product,” “asset,” and “inflation”

  28. A Ladder Of Abstraction For Concepts Vegetation Fruit Increasingly more abstract Banana Reality

  29. Scientific Business Researchers Operate at Two Levels • Abstract level • concepts • propositions • Empirical level • variables • hypotheses

  30. Definitions • Abstract level -In theory development, the level of knowledge expressing a concept that exists only as an idea or a quality apart from an object. • Empirical level -Level of knowledge reflecting that which is verifiable by experience or observation.

  31. Theory Building A Process Of Increasing Abstraction Theories Propositions Increasingly more abstract Concepts Observation of objects and events (reality )

  32. Concepts are Abstractions of Reality CONCEPTS Abstract Level Empirical Level OBSERVATION OF OBJECTS AND EVENTS (REALITY)

  33. Scientific Method The use of a set of prescribed procedures for establishing and connecting theoretical statements about events and for predicting events yet unknown.

  34. Abstract Level • Concepts abstract reality. • Propositions are statements concerned with the relationships among concepts.

  35. Proposition at Abstract Level Concept A (Reinforcement) Concept B (Habits) Hypothesis at Empirical Level Dollar bonus for sales volume over quota Always makes four sales calls a day

  36. A hypothesis is a proposition that is empirically testable. It is an empirical statement concerned with the relationship among variables. • A variable is anything that may assume different numerical values.

  37. Deductive Reasoning • The logical process of deriving a conclusion from a known premise or something known to be true. • We know that all managers are human beings. • If we also know that John Smith is a manager, • then we can deduce that John Smith is a human being.

  38. Inductive Reasoning • The logical process of establishing a general proposition on the basis of observation of particular facts. • All managers that have ever been seen are human beings; • therefore all managers are human beings.

  39. Falsificationist • You cannot prove the theory that it is correct, but you can disprove it.

  40. The Scientific Method: An Overview Assess relevant existing knowledge Formulate concepts & Propositions Statement of Hypotheses Design research Analyze & evaluate data Provide explanation- state new problem Acquire empirical data

  41. Scientific Observation Is Systematic “YOU SEE, BUT YOU DO NOT OBSERVE.” Sherlock Holmes

  42. What Can Be Observed? • Physical actions • Verbal behavior • Expressive behavior • Spatial relations and locations • Temporal patterns • Verbal and pictorial records

  43. What Can Be Observed Phenomena Example Human behavior or physical Shoppers movement action pattern in a store Verbal behavior Statements made by airline travelers who wait in line Expressive behavior Facial expressions, tone of voice, and other form of body language

  44. What Can Be Observed Phenomena Example Spatial relations How close visitors at an and locations art museum stand to paintings Temporal patterns How long fast-food customers wait for their order to be served Physical objects What brand name items are stored in consumers’ pantries Verbal and Pictorial Bar codes on product packages Records

  45. Categories of Observation • Human versus mechanical • Visible versus hidden • Direct • Contrived (artificial environment)

  46. Observation of Human BehaviorBenefits • Communication with respondent is not necessary • Data without distortions due to self-report (e.g.: without social desirability) Bias • No need to rely on respondents memory • Nonverbal behavior data may be obtained

  47. Observation of Human BehaviorBenefits • Certain data may be obtained more quickly • Environmental conditions may be recorded • May be combined with survey to provide supplemental evidence

  48. Observation of Human BehaviorLimitations • Cognitive phenomena cannot be observed • Interpretation of data may be a problem • Not all activity can be recorded • Only short periods can be observed • Observer bias possible • Possible invasion of privacy

  49. Observation of Physical Objects • Physical-trace evidence • Wear and tear of a book indicates how often it has been read

  50. Scientifically Contrived Observation • The creation of an artificial environment to test a hypothesis
