If you don't have coordinates of your data, as I understand here,
there's nothing you can do, of course ...
If you have coordinates, you should compute the variogram -and/or the
spatial covariance- of your data and look if they are meaningful.
Hint: read a book about geostatistics.

So, to me there is a light difference, but it's really "for advanced
users", and maybe questionable.
