Examples
-
At a 0.01 level of significance, the K-S statistic is equal to 1.63/square root of (n). If D is greater than the K-S statistic, then the sample distribution does not fit the theoretical distribution.

Morphology
The phrase is a direct composition of 'sample' (a subset taken for study) and 'distribution' (how values are spread), so a B1 learner who knows both words can infer it refers to the distribution of values in a sample. It is a technical statistical term with finer distinctions in advanced usage, but its basic meaning is transparently derivable from its constituents.
Etymology
The term sample distribution comes from the idea of taking a sample, a small part of a big group, and laying those items out to see their 'pattern' and how they are distributed. So, a sample distribution is the picture of those sample values and helps you guess what the whole group is like.
