Tests for randomness

Hi,

If I have a set of data points (14 to be exact) with an unknown
pedigree from a large population, what tests can I apply to see if they
constitute a random sample?

In a related question: if I knew a priori that the larger population
fell along a general distribution (say lognormal) and if a lognormal
line plot of this sub-data (14 points, unknown pedigree) fit rather
snugly, could I safely assume that my 14 data points were randomly
selected? Or would I be making a potentially damaging assumption?

Thanks,
-Stu
