question 20

Multiple Choice

• A)This experimental design controls for the effects of more extraneous variables than does the quasi-experimental one.
• B)Subjects are blind to group assignment in the experimental design but not in the quasi-experimental design.
• C)In the experimental version, there is better construct validity.
• D)This experimental design controls for the history threat to internal validity, whereas the quasi-experimental one does not.
• E)This experimental design controls for the testing threat to internal validity, whereas the quasi-experimental one does not.
