Experimental Designs Quiz

What is the main advantage of using independent groups in experimental designs?

• Higher validity

• Less effect of demand characteristics

• Order effects are not a problem

• Easier to match participants

What is a disadvantage of using independent groups?

• Higher validity

• Different people in each condition

• Less time needed in recruiting

• Less effect of demand characteristics

In repeated measures design, what is a potential issue participants might face?

• Order effects

• Different people in each condition

• Less effect of demand characteristics

• Matching is time-consuming

What is a key advantage of repeated measures design?

• Order effects are not a problem

• Higher validity

• Matching is time-consuming

• Different people in each condition

What is a matched pairs design?

• Participants take part in all conditions

• Participants are paired on a variable relevant to the experiment

• Participants experience only one condition

• Participants are randomly assigned to conditions

What is a disadvantage of matched pairs design?

• Higher validity

• Less effect of demand characteristics

• Matching is time-consuming and expensive

• Order effects are not a problem

What is counterbalancing in experimental design?

• Using different people in each condition

• Controlling order effects

• Pairing participants based on IQ

• Using fewer participants

Which experimental design uses fewer participants?

• Independent groups

• Repeated measures

• Matched pairs

• Random allocation

In a memory study using matched pairs, how are participants grouped?

• Randomly assigned to conditions

• Paired based on IQ scores

• All participants take part in all conditions

• Participants experience only one condition

What is a strength of using repeated measures design?

• Different people in each condition

• Less effect of demand characteristics

• Comparisons can be drawn easily

• Matching is time-consuming
