Controls sampling

The published calculation method and the company decisions it uses.

What Vanward calculates

Reproducible samples from the selected population.

The method

  1. Include every key item whose amount exceeds the entered threshold. Shuffle the remaining population with the saved numeric seed and select without replacement.
  2. Key items count toward the requested sample size. If key items exceed the size, keep every key item; otherwise fill the remaining places from the shuffled population.

What the company decides

Population completeness, control design, sample size, key-item threshold, evidence evaluation and test conclusions. These inputs and judgments are outside the guarantee.

Where it shows in Vanward

Controls tests, sampled populations and controls reports.
