Quiz on Major Experimental Designs in Psychological Research

What is the primary purpose of experimental designs in psychological research?

• To avoid ethical concerns

• To establish cause and effect relationships

• To collect qualitative data

• To manipulate variables

Which experimental design involves different participants assigned to separate groups?

• Pre Experimental Design

• Independent Measures Design

• Matched Pairs Design

• Repeated Measures Design

What is a key advantage of Repeated Measures Design?

• Reduces individual differences

• Requires a larger sample size

• Avoids ethical concerns

• Minimizes variability between groups

In which design are participants paired based on similar characteristics?

• Pre Experimental Design

• True Experimental Design

• Independent Measures Design

• Matched Pairs Design

What is a limitation of Pre Experimental Designs?

• Lack of random assignment

• Minimization of variability

• High control over variables

• Ability to establish cause and effect

Which design provides high levels of control over variables through random assignment?

• True Experimental Designs

• Pre Experimental Designs

• Matched Pairs Design

• Independent Measures Design

What is a major strength of experimental designs?

• Limited applicability

• Low cost

• Complexity in analysis

• High control over variables

What is a potential ethical concern in experimental designs?

• Replicability

• Artificial settings

• High control over variables

• Participant treatment

What is the purpose of using randomization in experimental design?

• To reduce costs

• To eliminate selection bias

• To increase sample size

• To control for ethical concerns

Which of the following is a characteristic of Complex Group Designs?

• Focuses solely on qualitative data

• Requires a smaller sample size
