Experimental Design

Question 1

Independent Measures Design

Answer 1

Participants only take part in one condition of the experiment. (2 groups)

Question 2

Individual Differences (Independent Measures Design Evaluation)

Answer 2

When differences between the groups causes the results, not the independent variable, in this way they are confounding variables.

Question 3

Randomization (Independent Measures Design Evaluation)

Answer 3

Randomly assigning participants to conditions to reduce individual differences and experimenter bias.

Question 4

Repeated Measures Design

Answer 4

Participants take part in both conditions of the experiment. (1 group)

Question 5

Order Effects (Repeated Measures Design Evaluation)

Answer 5

When the order of the conditions affects the participants behavior.

Question 6

Counter Balancing (Repeated Measures Design Evaluation)

Answer 6

Half the participants do Condition 1, then 2, the other half of the participants do Condition 2, then 1. So, all participants are still doing all conditions of the IV. This reduces order effects.

Question 7

Matched Pairs Design

Answer 7

Participants are matched in each condition for characteristics that may have an effect on their performance memory test e.g. IQ, gender.

Question 8

Matched Pairs Design Evaluation

Answer 8

Similar to independent design, yet you’ve tried to stop individual differences by having similar people.
