Hey all,

I have set up an experiment where I want to assess the effect that angle, distance and measuring method has on measurements made using stereo-photographs. I want to find out if they significantly influence the measurements and to what degree and also if there is an interaction occurring with distance*angle.

What statistical test should I use? I have asked around but have been told conflicting answers (Factorial ANOVA, General linear model, nested ANOVA), so I am unsure on how to proceed.

So there were 7 different angles and within each angle a photograph was taken at 4 distances 40,50,60,70 metres from the object of interest (which is two stakes measuring 6 metres apart) also the photographs were measured in two different ways, manual and automatic.

Hope this makes sense, and thanks in advance for you advice

Cheers,
Abe
