Week Six - Factorial Repeated Measures

Question 1

What are the design possibilities with a factorial ANOVA?

Answer 1

BS, WS and Mixed

Question 2

Explain Fixed and Random factors?

Answer 2

Fixed: IV levels are chosen and do not change randomly from one experiment to the next

Random: IV levels are randomly selected from a larger population of potential levels. Differ from one replication to the next (e.g., subjects)

Question 3

Does sphericity still apply?

Answer 3

Yes - if there are more than 2 levels on any WS IV then it is likely there is violation

Question 4

Rather than using paired t-tests to investigate sig interaction in FRM, what can you do?

Answer 4

Do two separate one-way repeated measures ANOVAs with BA

Question 5

What is a mixed factorial design?

Answer 5

both within and between subjects IVs

Question 6

Should we look at HOV or sphericity in MFA?

Answer 6

Both with potential of GG

Question 7

Explain crossed and nested factors?

Answer 7

Crossed: all levels of B occur in all levels of A
Nested: different levels of B at each level of A
