Multivariate Experimental Designs

Question 1

Multivariate experimental design

Answer 1

2+ DVs
Collect multiple measures of behavior in a single exp.
Advantages:
-Economical use of time/resources
-Increase chance of finding sign. effects

Question 2

Converging operations

Answer 2

• Use diff. operational def. of same variable

- > If same results regardless, increase generality of conclusion

Question 3

Converging series of exp.s

Answer 3

WHEN

• If single exp. cannot include all relevant tests
• If several hyp. can account for same finding, and single exp. cannot determine best hyp.
• Involves partial (built-in) replications
• Req. at least some between-sub. comparisons

Question 4

Distributes practice

Answer 4

Spaced learning -> memory consolidation

Multiple contexts
