What are the key differences between a multiple group experiment and a classical randomized experiment with only two groups?
What will be an ideal response?
The only difference between a classical randomized experiment and multiple group experiment is that in a multiple group design more than one experimental or control groups are created so that different levels of the experimental variable can be compared. This is useful if the independent variable can assume several values or if the researcher wants to see the possible effects of manipulating the independent variable in several different ways—or test multiple treatments. Multiple group designs may involve a post-test only or both a pre-test and a post-test. They may also include a time series component.
