Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to determine the level of order of a pattern of particles on a sample surface. One idea was to calculate the mean distance between one particle and those adjacent and compare them to the idealised (perfect grid arrangment) distance if I take the area of the surface divided by the number of particles. Would this be the right path to go down:yuck: ? If so, what statistical criterion could I use to determine whether a particle is adjacent or not?

All the best,

James
