Psych Research Pt 8

Interpreting ANOVAs

QuestionAnswer
Why do an ANOVA instead of multiple t-tests? multiple t-tests are more work and inflate the type I error rate
MSwithin measure of variability in the DV due to error
F measures how many times greater MStreat than MSwithin, thus whether IV is affecting the DV
MStreat measure of the variability in the DV is due to IV or error
ANOVA Summary Table - Lines 3 lines = between subjects 1-way 4 lines = within subjects 1-way 5 lines = between subjects factorial
How to find IV levels? add 1 to df
DF of F-Ratio numerator = same line denominator = line above total
Feffect MSeffect/MSerror or MSwithin
MSeffect SSeffect/dfeffect
