Match the LIST-I with LIST-II:

LIST-I	LIST-II
A. Pre-experimental design	I. Involves manipulation of independent variable with random assignment
B. True-experimental design	II. Lack of randomization and control group
C. Quasi-experimental design	III. Examines the interaction effect of multiple independent variables
D. Factorial design	IV. Lack of randomization but includes some control

Options:

Correct option is B

Correct Matching:

• A. Pre-experimental design: This design lacks randomization and control groups. It typically involves a single group, and there is no random assignment of participants.
• B. True-experimental design: This design involves random assignment to control and experimental groups, with manipulation of the independent variable to determine cause and effect.
• C. Quasi-experimental design: This design lacks randomization but includes some control, often used when random assignment is not feasible.
• D. Factorial design: This design examines the interaction between multiple independent variables to understand their combined effects on the dependent variable.

Information Booster:

1. True-experimental design is considered the most robust because of randomization, which helps eliminate biases and confounding variables.
2. Quasi-experimental designs are used when randomization is not possible, but some control group is still used.
3. Factorial designs are useful for examining the interaction between two or more independent variables.

Additional Knowledge:

• Factorial designs are commonly used in experimental psychology and education to examine how different factors interact with each other.
• Pre-experimental designs are often used in initial stages of research where the researcher has limited control over variables.
