Introduction to SDS/MTH 290

What Makes a study an "Experiment"?

  • Can you assign experimental material to conditions?
  • If the material alredy comes in different “varieties”, then it's an observational study
    • For example, samples of people with different psychiatric illnesses
    • Different species of plants
  • Sometimes one “study” will have both experimental and observational variables

Discussion questions

  • What were all of the possibilities?
  • Did everyone see all of the possibilities? If not, how do you think that was determined?
  • Which pieces were distributed across people, and which within people?
  • What do you think are the possible research questions answered by this study?
