Introduction to Research Concepts using the Card Probability Study Chapter 1 Thomas and Nelson

How does the card probability study, conducted in the previous class, fit into the basic to applied research continuum?

In what ways was the study lacking in ecological validity? How does this relate to the internal and external validity of the study?

Is It better to stay of to switch What would have been the problem statement for the card probability study?

1) There is more chance to win if you stay 2) There is more chance to win if you change 3) You will have to same amount of chance to win regardless if you stay or switch List three potential hypotheses that could have been put forth prior to the study.

1) Tenacity : Superstitious, its always the left card 2) Intuition : Gut feeling, I picked this card so it must be right 3) Authority : Someone of high status told us so 4) Rationalistic method : If there are two cards left and one’s a loser and ones a winner then there is a chance of winning 5) Empirical : Self gathering of data without a real proof Provide four unscientific methods of problem solving and give an example of how each could be applied to solving our problem statement.

Dependent: The percentage of winning or losing Independent: The choice of staying or switching (2 levels) What were the independent and dependent variables in the study? How many levels of each independent variable were there?

Yes: manipulation of independent variable. Was the study experimental in nature? Explain
