  1. Introduction to Research Concepts using theCard Probability Study Chapter 1 Thomas and Nelson

  2. How does the card probability study, conducted in the previous class, fit into the basic to applied research continuum? • Fits in the middle • Basic because we had control of the fixing of groups • Applied if it was in a casino situation.

  3. In what ways was the study lacking in ecological validity? How does this relate to the internal and externalvalidity of the study? • Ecological Validity-how does our experiment relate to the real world? We controlled most of the variables. We decided if we would stay or change. If we wanted it to be more ecologically valid, we would just allow the game to be played. • External validity is very similar to ecological validity. • Internal Validity.

  4. What would have been the problem statement for the card probability study? • Is it better to stay or switch? Is our problem statement.

  5. List three potential hypotheses that could have been put forth prior to the study. • If you stay • if you switch • both the same

  6. Provide four unscientific methods of problem solving and give an example of how each could be applied to solving our problem statement. • Empirical • Intuition • Authority • The Rationalistic Method

  7. What were the independent and dependent variables in the study? How many levels of each independent variable were there? • Independent is the choice to stay or switch • Dependent is the percentage of winning

  8. Was the study experimental in nature? Explain • Yes it was. We manipulated the variable because we chose what groups stayed with their original card or switched to a new card.
