writing anova results for a paper

Hi all,

It is first time that I am trying to write a scientific paper based on statistical analysis and i am a bit confused.

The results from my anova analysis are

The GLM Procedure

Dependent Variable: ratio

Sum of
Source DF Squares Mean Square F Value Pr > F

Model 6 1.10360473 0.18393412 3.83 0.0135

ni 1 0.59001854 0.59001854 12.27 0.0027
su 1 0.02786590 0.02786590 0.58 0.4569

replicate 2 0.17634358 0.08817179 1.83 0.1900

the model significance is higher than the significance in the type III error.

When I am writing the paper and refering to the individual factor effect should i use the signicance level of the Type III error (which lower than the model) or the p-value of the model?

depends on the jounral, but usually its the p-value:

for example, the GLM model showed a significant effect of.. (F1,34 = Fvalue; P=0.01).

I'd advise you to look at examples of the Jounral you are submitting to.
well with significant difference I was refering to the p-value (sorry but I suck in statistics),
but I don't know if it should be the p value of the model or the p value of the seperate factor effects

Model if you are saying overall there was a difference.

If you are reporting on the specific factors then use the factor effects
