Symbols and units
- a
- Dataset
- b
- Percentile (%)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
quantile(list, p): sort values ascending, let k = (count−1) × p, and linearly interpolate between the entries at floor(k) and ceil(k), counting positions from zero. Other percentile conventions may differ.
Assumptions & limits
Assumptions & limits
- Uses linear interpolation at sorted index (n−1)p. Lists support up to 1,000 finite values.
