Research Variables Quiz

What is an extraneous variable?

• A variable that systematically changes with the IV

• A variable that affects the DV if not controlled

• A variable that is the same as the IV

• A variable that is always controlled

What is a confounding variable?

• A variable that does not affect the DV

• A variable that changes systematically with the IV

• A variable that is always independent

• A variable that is irrelevant to the study

What are demand characteristics?

• Variables that are always controlled

• Cues that may influence participants' behavior

• Variables that are irrelevant to the study

• Factors that never affect the DV

What does standardisation involve in a research study?

• Using different procedures for each participant

• Using the same procedures for all participants

• Changing the IV for each trial

• Ignoring the DV

Why is it important to control extraneous variables?

• To ensure they become confounding variables

• To prevent them from affecting the DV

• To make the IV irrelevant

• To increase the number of confounding variables

What might participants do in response to demand characteristics?

• Ignore the experiment entirely

• Change their behavior based on perceived expectations

• Always follow the exact instructions

• Never alter their behavior

What is the role of investigator effects in research?

• They have no impact on the research outcome

• They can influence the DV through the investigator's behavior

• They always improve the research results

• They are irrelevant to the research process

Diagram question regarding participant behaviors in experiments.

• Participants follow instructions accurately.

• Participants deviate from instructions.

• Participants show no response.

• Participants exhibit unexpected behaviors.
