Bu hasapçy hakda
A percentile is the value below which a given percentage of the data falls — the 90th percentile is the point beneath which 90% of the values lie. Percentiles turn a raw number into a rank you can interpret: a test score at the 90th percentile beat 90% of the other scores.
This calculator uses the linear-interpolation method, the same as the spreadsheet PERCENTILE.INC function. It sorts the data, computes a rank of (p ÷ 100) × (n − 1), and if that rank falls between two positions it interpolates linearly between the neighbouring values. It also returns the full five-number summary (minimum, first quartile, median, third quartile and maximum) and the interquartile range.
Worked example: for 5, 7, 8, 12, 14, 18, 21, 25, 30, 35 (ten values) the 90th percentile has rank 0.90 × 9 = 8.1, which lies between the values at positions 8 and 9 (30 and 35); interpolating 0.1 of the way gives 30 + 0.1 × 5 = 30.5. A table below gives the percentile rank of every value, which is handy for growth charts, exam scoring and benchmarking.
