Experimental Design And Observational Design Flashcards
1
Q
Independent measures
A
Ppts take part in one condition of experiment
2
Q
Repeated measures
A
Ppts take part in all condition of experiment
3
Q
Matched pairs
A
Ppts matched each condition for characteristics may affect performance
4
Q
Independent measures strengths
A
-less order effects
-less demand characteristics
5
Q
Independent measures weaknesses
A
-ppts different so difference in DV could be due to individual
-less economical more Ppts required
6
Q
Repeated measures strengths
A
-more economical
-no Ppts variables
7
Q
Repeated measures weaknesses
A
-order effects
-demand characteristics
8
Q
Matched pairs strengths
A
.ppts variables reduced
.only take part one condition of IV
.Less likely guess aim of experiment
9
Q
Matched pairs weaknesses
A
-Ppts never be exactly matched
-time consuming + expensive
