I-Calculator ye-Percentile
Thola ixabiso nganoma yisiphi isiphesenti kanye nequartiles yeset data.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Uhlu lwezinhlamvu
Idatha ihlukaniswe futhi isikhundla se (p/100)·(n − 1) sibalo. Uma lesi sikhundla siyinombolo egcwele, ixabiso kulolu hlangothi libuyiselwa; ngamanye amaxesha i-calculator i-interpolates linearly phakathi kwamaxabiso amabini asendaweni. Le yindlela ebandakanyayo (PERCENTILE.INC).
Yini ushintsho phakathi kwe-percentile ne-quartile?
Ama-quartiles ayizinkulungwane ezikhethekile ezihlukanisa idatha ibe ngamangxenye amane alinganayo: inkulungwane yokuqala yinkulungwane engu-25, eyesibili yinkulungwane engu-50 (iphakathi) futhi yesithathu yinkulungwane engu-75.
Yini ibanga le-interquartile?
I interquartile ubukhulu (IQR) yi-quartile yesithathu ngaphezu yokuqala - ibanga lephakathi 50% yedatha. Ngenxa yalokho, i ignores iphezulu nephansi kwekota kuyinto ukuhlolwa okuqinile kokusabalalisa futhi njalo kusetshenziswa ukuphawula outliers.
Yini okushoyo i-90th percentile?
Ixabiso elingaphansi kwe-90% yedatha ikhona, ngakho-ke i-10% kuphela yezimpendulo ziphezulu. Ukunqoba kwi-90th percentile kuvavanyo kusho ukuthi wenze kahle kunalokho okungo-90% kwabanye abathatha ukuhlolwa.
Ingabe i-percentile engu-50 ifana ne-median?
Yebo. I-50th percentile ihlukanise idatha ukuze inhlamvu yesigamu semali idlule ngaphansi kwayo, okuwukusho okucacile kwe-median.
Kungani ithuluzi elisha linganikeza isenti elihlukile?
Kunezichazamazwi eziningi ezivunyelwe ze-percentile. Le kalkuli isebenzisa ukufaka phakathi okuqondile (PERCENTILE.INC); indlela ekhethekile (PERCENTILE.EXC) kanye nendlela ephakathi-no-ranger ibeka i-percentile ngokuhlukile, ngakho-ke izimpendulo zingahluka kancane phakathi kwamathuluzi, ikakhulukazi kumasethingi amancane wedatha.
API — sebenzisa le calculator kusuka kukhodi
Nquma le calculator njenge JSON evulekile yendawo yokuqeda - akukho isithonjana esidingekayo. Thumela amaxabiso endawo ngezansi njengezilungiselelo zombuzo noma i-JSON. Noma yini ongayishiya isebenzisa iphutha elifanayo elifakwe ngaphambili lekhasi; ipharamitha engaziwa yi-400, ayikho i-zero emnyama. Funda i-API egcwele →
