Understanding Experimental Designs

What is the primary goal of a true experimental design?

• To explore naturally occurring behaviors

• To establish cause and effect relationships

• To describe phenomena without manipulation

• To study pre-existing groups

Which feature of true experimental design helps reduce bias?

• Observational techniques

• Random assignment of participants

• Use of pre-existing groups

• Manipulation of dependent variables

What is a major strength of true experimental design?

• Low cost and time efficiency

• Ability to determine causation with confidence

• High external validity

• Flexibility in variable control

What is a common limitation of true experimental design?

• Time-consuming and expensive nature

• Low internal validity

• Inability to replicate studies

• Lack of control over variables

Which alternative method to true experimental design does not use random assignment?

• Quasi-experimental design

• Case studies

• Longitudinal studies

• Correlational research
