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.

Kodi ndi percentile anawerengedwa?
The data ndi osiyanasiyana ndi mlingo wa (p / 100) · (n - 1) ndi anawerengedwa. Ngati kuti mlingo ndi inali
Kodi pali kusiyana kotani pakati pa percentile ndi quartile?
Quartiles are just specific percentiles that split the data into four equal parts: the first quartile is the 25th percentile, the second is the 50th (the median) and the third is the 75th percentile.
Kodi ndi chiyani interquartile mlingo?
Mtundu wa Interquartile (IQR) ndi wachitatu quartile minus the first - span ya pakati 50% ya deta.Popeza amasiya kuganizira pamwamba ndi pansi kwa chaka ndi yolimba mfundo ya kufalitsa ndi nthawi zambiri amagwiritsa ntchito kusonyeza outliers.
Kodi 90th percentile zikutanthauza chiyani?
Ndi mfundo pansi pa zomwe 90% ya deta limati, choncho 10% ya zowonera ndi pamwamba. Kupambana pa 90th percentile pa mlingo kumatanthauza kuti inu anachita bwino kuposa pafupifupi 90% ya ena mlingo-wotenga.
Kodi 50th percentile ndi chimodzimodzi monga median?
Ndikofunika. The 50th percentile amagawa deta kuti theka la matanthauzo afika pansi pa izo, amene ndi moyenera tanthauzo la median.
N’chifukwa chiyani chida china chikhoza kupereka percentile yosiyana pang’ono?
Pali matanthauzo ambiri ovomerezeka a percentile. Izi calculator amagwiritsa ntchito kuphatikiza linear interpolation (PERCENTILE. INC); njira yokhayo (PERCENTILE. EXC) ndi njira ya kuzungulira- rank kuika percentile pang'ono mosiyana, kotero zotsatira zingasiyana pang'ono pakati pa zida, makamaka pa ma seti a data ochepa.
