(Experimental and Quasi-Experimental)
The primary use of the classic experimental design -- Cause-effect relationship
Three conditions that must be met in order to establish a cause-effect relationship
1. Timing 2. Association 3. Non- Spurious
Four components of the classic experimental design
1. Intervention 2. Exp / Control 3. Pre / Post test 4. Random Assignment
Differences between The quasi-experimental design and the experimental design: No Random Assignment
Advantages of the experimental design -- Flaw in a quasi-experimental design: Pre-existing group differences
