  1. Research Design How to do a research project!

  2. Research designs can be very simple:

  3. Or…. quite complicated!

  4. Or… something in between!

  5. A good design will not compensate for bad fundamentals!

  6. Research Design A formal written set of specifications and procedures for

  7. There are many ways to set up a Research Design So we will look at a generic plan.

  8. Research Design A formal written set of specifications and procedures for Conducting and Controlling a business research project

  9. DESIGN controlsfor: Time

  10. DESIGN controls for: Time Money

  11. DESIGN controls for: Time Money People

  12. A good DESIGN ensures: • The study will be relevant • That is will use economic procedures

  13. Problem: The Law of the Instrument

  14. Types of Designs • Exploratory Research to gain insight and ideas… It is for understanding… not for analysis

  15. Types of Designs • Exploratory Flexible… good for: • Diagnosing a situation • Screening alternatives • Increase research’s familiarity with problem • Discovery of new ideas

  16. Types of Designs Be careful: Gas lights:

  17. Types of Designs Be careful: IBM study in 1947:

  18. “On a humorous note, the principal designer of the Mark I, Howard Aiken of Harvard, estimated in 1947 that six electronic digital computers would be sufficient to satisfy the computing needs of the entire United States. IBM had commissioned this study to determine whether it should bother developing this new invention into one of its standard products (up until then computers were one-of-a-kind items built by special arrangement). Aiken's prediction wasn't actually so bad as there were very few institutions (principally, the government and military) that could afford the cost of what was called a computer in 1947.

  19. Types of Designs • Exploratory Flexible… good for: • Diagnosing a situation • Screening alternatives • Increase research’s familiarity with problem • Discovery of new ideas • Gathering background info

  20. Types of Designs • Exploratory Methods: • Situational analysis

  21. Type of Designs • Exploratory Methods: • Situational analysis • Expert Opinion survey

  22. Types of Designs • Exploratory Methods: • Situational analysis • Expert opinion survey • Literature search • Pilot study • Focus groups

  23. Types of Designs • Exploratory • Descriptive a.To describe characteristics of a sample

  24. Type of Designs • Exploratory • Descriptive a.To describe characteristics of a sample b. To estimate proportions

  25. Type of Designs • Exploratory • Descriptive Cross-Sectional

  26. Types of Designs • Exploratory • Descriptive Longitudinal

  28. Types of Designs • Exploratory • Descriptive Longitudinal Omnibus

  29. Types of Designs • Exploratory • Descriptive Longitudinal Panels

  30. Types of Designs • Exploratory • Descriptive Longitudinal Panels Problems: Lack of representation They become experts

  31. Type of Designs • Exploratory • Descriptive • Associational What goes with what?

  32. S&P 500

  33. Types of Designs • Exploratory • Descriptive • Associational • Casual (Experiments)

  34. Types of Designs Casual (Experiments) Concept of Causality • Concomitant variation • Time order (casual order) • Elimination of alternative explanations

  35. Types of Designs Casual (Experiments) Key is: Control

  36. Types of Designs Casual (Experiments) Terms:

  37. Types of Designs Casual (Experiments) Terms: Variable

  38. Types of Designs Casual (Experiments) Terms: Constant

  39. Types of Designs Casual (Experiments) Terms: IV Independent Variable: treatment exogenous

  40. Types of Designs Casual (Experiments) Terms: DV Dependent Variable: measurement endogenous

  41. Types of Designs Casual (Experiments) Terms: Secondary Variables Something to be controlled that could cause the DV to change… Extraneous

  42. Types of Designs Casual (Experiments) Terms: Secondary Variables • Eliminate them • Make them constant • Turn them into IVs • Randomization • Statistical control

  43. Types of Designs Casual (Experiments) Terms: Field Experiment Split-plot

  44. Types of Designs Casual (Experiments) Terms: Laboratory Experiment

  45. Validity Issues

  46. Validity Issues Internal Validity The effect is due to IV and Not to other variables
