Experimental Design |
This is the way the conditions of an experiment are set up |
|
|
3 Measures |
Independent Measures Respected Measures Matched Participants |
|
|
Independent Measures |
Recruit a group of participants, divide into 2. Group A - Condition 1 Group B - Condition 2. Measure the DV for each group. Compare results. |
|
|
Repeated Measures |
Recruit a group of Participants, group does both conditions. |
|
|
Matched Participants |
Recruit a group of participants. Look at characteristics. Independent Measures, group B made of ppts like group A |
|
|
Problems |
Individual Differences Intelligence, social class, memory More likely to occur in independent Measures. |
|
|
Ways to control ppt variables |
Use repeated Measures designs Use matched pair design Careful selection of participants Randomly assign people to conditions. |
|
|
Order effects? |
Occur when a repeated Measures design is used 1) Practice 2) Fatigue |
|
|
How to control order effects |
Counter- balancing - Half do condition A - half do condition B ABBA Or- leave a long gap between condition |
|
|
Strength of Matched Measures |
No order effects Low individual Differences |
|
|
Weaknesses of Matched Measures |
Time consuming |
|
|
Strength of Repeated Measures |
Fewer participants needed Fewer participant variable |
|
|
Weaknesses of repeated |
Order effects |
|
|
Strengths of Independent Measures |
Low confounding variables No order effects |
|
|
Weaknesses of independent |
