Construction of a Research Design


1.    Observations or Measures
2.    Treatments or Programs
3.    Groups
4.     Assignment to Group

Characteristics of Good Design

  • Theory-Grounded: Reflects the theories which are being investigated
  • Situational: Indicates the settings or conditions of the investigation
  • Feasible: Can be implemented
  • Redundant: Provides multiple processing particularly for validation
  • Efficient: Maintains a balance between redundancy and the tendency to over-design

Examples of Research Design

  1. Laboratory Experiments (JIS, ASTM, Euro, PNS, etc) and Regression Analysis
  2. Prototyping and Descriptive Statistics
