What threats to internal validity are reduced when you switch from a one group pretest-posttest to a static comparison group design? What potential threat is introduced?

What will be an ideal response?


When you use a static comparison group design instead of a one group pretest-posttest design, you can reduce the threats of history and maturation. (History can still exist if the two groups are separated so that one is affected by outside events that don't affect the other.) By including a second group in the static comparison group, though, you now have to worry about selection threats if your groups are nonequivalent.
