4. Psych Research Design Evaluation

What is the main advantage of using a repeated measures design?

• It eliminates the need for a control group

• It reduces the impact of individual differences

• It increases the likelihood of demand characteristics

• It simplifies the data analysis process

Which of the following is a potential disadvantage of using a matched pairs design?

• It requires a large sample size

• It is difficult to find perfectly matched pairs

• It increases the risk of order effects

• It eliminates the need for random assignment

What is the main purpose of counterbalancing in an experimental design?

• To increase the sample size

• To control for order effects

• To ensure random assignment

• To manipulate the independent variable

Which of the following is a strength of using a laboratory experiment?

• High ecological validity

• High control over extraneous variables

• High generalisability

• High external validity

What is the main disadvantage of using a field experiment?

• Low ecological validity

• Low control over extraneous variables

• Low internal validity

• Low external validity

Which of the following is a method to ensure that participants are unaware of the specific aims of the study?

• Informed consent

• Debriefing

• Single-blind procedure

• Random assignment

What is a key advantage of using a double-blind procedure in an experiment?

• It increases the sample size

• It controls for both participant and experimenter biases

• It ensures random sampling

• It simplifies the data collection process

Which of the following is a potential drawback of using a natural experiment?

• Low ecological validity

• Low control over extraneous variables

• High internal validity

• High control over the independent variable

What is a primary benefit of using a within-subjects design?

• It requires fewer participants

• It eliminates the need for a control group

• It increases the risk of carryover effects

• It simplifies the data collection process

Which of the following is a potential issue with using a between-subjects design?

• It increases the risk of order effects

• It requires a larger sample size

• It reduces the impact of individual differences

• It simplifies the data analysis process
