  2. Case Study
    • A research strategy in which the researcher's attention centers on an in-depth examination of one or a few cases on many dimensions
    • Cases studies can be exploratory, descriptive, or explanatory.
  3. Classical Experiment

  8. Random Assignment

  9. Variable-Oriented Research
