Psychology research methods 4

Experimental design is about how:

• The IV is manipulated.

• The DV is measured.

• Participants are allocated to conditions.

• Many conditions of the IV there are.

Which design has two or more conditions of the IV?

• Independent groups.

• Repeated measures.

• Matched pairs.

• All of the above.

Practice and boredom are

• Order.

• Participant.

• Experimental.

• Repeated.

Practice effects are a problem with:

• Independent groups.

• Repeated measures.

• Matched pairs.

• All designs.

Participant variables arise in:

• Repeated measures.

• All designs.

• No designs.

• Independent groups.

In which design are participants most likely to guess the study's aim?

• Independent groups.

• Matched pairs.

• Repeated measures.

• Field experiment.

Which design uses half the number of participants of the others?

• Independent groups.

• Repeated measures.

• Matched pairs.

• Natural experiment.

Participants are studied on several occasions over time in:

• Cross-sectional studies.

• Independent groups.

• Longitudinal studies.

• Matched pairs.

A kind of extraneous variable:

• A co-variable.

• A confounding variable.

• An independent variable.

• A dependent variable.

In a poorly-designed experiment, any change in the DV could be due to:

• The IV, extraneous variables or confounding variables only.

• The IV and extraneous variables only.

• The IV and confounding variables only.

• The IV only.
