Experimental Design

Question 1

Repeated Measure Design

Answer 1

The same participants are allocated to all groups

Question 2

Repeated Measure Designs (Strengths)

Answer 2

Extra participants don’t need to be used, the same participants are used

Question 3

Repeated Measure Designs (Weakness)

Answer 3

There is a risk of order effect (Demand Characteristics)

Question 4

Repeated Measures Design

How can order effect be countered?

Answer 4

Counterbalancing

The sample is split in half with one half completing two conditions in one order and the other half completing the conditions in the reverse order

Question 5

Independent Group Designs

Answer 5

Different participants take part in each experimental condition (randomly allocated)

Question 6

Independent measure design (strength)

Answer 6

No order effect, as participants will only partake in one condition

Question 7

Independent measure Design (Weakness)

Answer 7

Risk of Participant variables, affecting the results between conditions rather than the manipulation of the IV

Question 8

Matched pair Designs

Answer 8

Participants take part in only one experimental condition, they are recruited specifically to be similar in relevant characteristics (Age, Intelligence, Gender) to matched participants in the other conditions

Question 9

Matched pair designs (Strength)

Answer 9

No chance off Order effect, participants only take part in one condition

The participant matching process reduces participants variables

Question 10

Matched pair designs (Weakness)

Answer 10

Matching is a more complex process, it will always be difficult to match participants identically
