Two hypothetical outcomes for the same repeated-measures experiment are shown. Outcome A Outcome B
Treatment Treatment
Participant I II III Participant I II III
A 50 63 50 A 50 55 60
B 54 56 62 B 51 56 61
C 58 51 57 C 50 57 61
D 60 55 52 D 52 58 63
For each outcome, consider the scores and note how they vary from treatment to treatment and from participant to participant (without making any calculations).
Outcome A appears to havebetween-treatments variance than (as) outcome B.
Outcome A appears to haveerror than (as) outcome B.
You can predict that outcome A hasF-ratio than (as) outcome B.
