How Percentile Rank Calculator works
Calculate a midrank percentile as 100 × (below + half the equal count) / n.
Use 1–1,000 comma- or whitespace-separated numbers, each with magnitude at most 1 billion. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded. This is an empirical midrank convention, not interpolation or a normal-distribution probability. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded.
