2. _____________are those where researchers have complete control over the extraneous variables & can predict confidently that the observed effect on the dependable variable is only due to the manipulation of the independent variable

• Manipulation

• Control

• Randomization

• True experimental design

Which of the following is NOT an essential characteristic of a true experimental design?

• Control

• Randomization

• Manipulation

• Specification

4. This means that every subject has an equal chance of being assigned to experimental or of study subject on a random basis.

• Control

• Randomization

• Manipulation

• Experimental design

5. In this design, there are two experimental groups (experimental group 1 & 2) & two control groups(control group 1 & 2)

• Post-Test Only

• Solomon Four-Group Design

• Factorial Design

• Randomized Block Design

•When there are a large number of experimental comparison groups, the__________________ is used to bring homogeneity among selected different groups

• Randomized block design

• Pre-Test and Post test Only

• Post-Test Only

• Cross over Design

7. •This design is also known as “repeat measure design.”

• Random Block Design

• Pre-Test Post Test Only

• Cross Over Design

• Post-Test Only

8. In _____________design, researcher manipulates two or more independent variables simultaneously to observe their effects on the dependent variables.

• Random Block Design

• Factorial Design

• Cross Over Design

• Solomon Four-Groups

•Experimental design are considered the most powerful designs to establish the causal relationship between ____________________ & _____________________variables.

One of the advantage of experimental design is most of the time, the results of experimental research designs cannot be replicated in studies conducted on human beings due to ethical problems.
