Look at plots of the row means and column means (of the new data).
They are far from flat.

Hi guys,
I am quite a newbie in engineering, so apologies for such a simple question.
Essentially, I have a collected data from a process that is a function
of two variables, say x and y. When I plot the measured data vs. the
two variables, I obtained a surface plot, with the height being the
magnitude recorded at (x,y). It is very easy to see that, although very
noisy, the surface is essentially flat. I would like to perform some
kind of statistical test in order to prove that it is indeed flat, but
I just do not know how to do that. Any help would be much appreciated.
