How Percentile Calculator works

Find a percentile by linear interpolation in sorted data.

Up to 1,000 values, separated by commas or whitespace. Repeated observations count separately. Finite real numbers only. Display uses up to 12 significant digits; binary floating-point arithmetic can introduce rounding. Uses index (n − 1) × p / 100, sometimes called the inclusive or R-7 method. Other percentile conventions may differ.
