About this data sampler
Paste one item per line and pick a method: Random N draws without replacement via a partial shuffle; Every Nth is classic systematic sampling — a random start point, then one item every N-1 lines; First N simply takes the head of the list. The sample size N and an optional numeric seed fully determine the outcome.
With a seed set, a mulberry32 PRNG drives the draw so identical inputs always produce identical samples — great for review and demos. Leave it empty to use cryptographically strong randomness. Total and picked counts are shown under the result, ready to copy into a sheet or document.
