Complete the table of statistical techniques over the course of the week and describe what is the difference between the different techniques. Make sure you use the discussion board to ask questions and to clarify techniques. (I completed the Independent Samples t-test to start the process; I expect the terms to be a bit difficult, so I really want this discussion to be a learning experience)
Here are some definitions:
- IV=Manipulation; Levels of IV=how many groups;
- Fixed=participants take on one value (i.e., group 1 or group 2);
- Random=participants can take on any value (e.g., amount of depression).
- Between Subjects=different people in each group (fixed) or different amounts of IV (random)
- Within Subjects=same people measure repeatedly
- # of DVs=how many outcomes are used in the statistical technique.
