Experimental Design

Question 1

What is a repeated measures design?

Answer 1

Ppts take part in all conditions

Question 2

What is a strength of a repeated measures design?

Answer 2

Removes individual differences, more cost effective as less ppts are needed

Question 3

What is a weakness of a repeated measures design?

Answer 3

Ppts may get bored as a result of repeating the experiment conditions

Question 4

What is an independent group design?

Answer 4

Each ppt takes part in one condition only

Question 5

What is a strength of an independent group design?

Answer 5

Reduced risk of demand characteristics, no order effects

Question 6

What is a weakness of an independent group design?

Answer 6

Individual differences, avoid this with random allocation

Question 7

What is a matched pairs design?

Answer 7

Ppts are matched on key characteristics relevant to the study each ppt does a different condition

Question 8

What is a strength of a matched pairs design?

Answer 8

Reduced demand characteristics, less individual differences, no order effects

Question 9

What is a weakness of a matched pairs design?

Answer 9

Investigator has more control over ppr selection, most exspensive
