Hi,
perhaps the question I have is more a statistical question than a
question about R.
But I hope nevertheless someone could help me.
If I have the following anova table;
Analysis of Variance Table
Response: aktiv
Df Sum Sq Mean Sq F value Pr(>F)
fac1 1 0.1091 0.1091 1.1207 0.291156
fac2 1 0.2035 0.2035 2.0903 0.149935
fac3 1 0.9400 0.9400 9.6568 0.002186
**
fac4 1 0.2338 0.2338 2.4018 0.122912
fac1:fac2 1 0.0273 0.0273 0.2809 0.596754
fac1:fac3 1 0.0528 0.0528 0.5426 0.462309
fac2:fac3 1 0.0122 0.0122 0.1252 0.723902
Residuals 184 17.910 0.0973
How do I compute eta^2 for factor 3 (fac3)?
Can I just calculate it over the sum squares?
Like 0.9400 / (0.1091 + 0.2035 + 0.9400 .... + 0.0122 + 17.910);
is that my eta^2?
How would I report the results?
(Like F(1,184) = 9.65 ..?)
(don't you have always two degrees of freedom in an Anova?)
thanks for any help!
