Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Sidee ayaa boqolkiiba la xisaabiyey?
Data waa la kala soocay oo heerka (p / 100) · (n - 1) waa la xisaabiyaa. Haddii heerkaas waa tirada buuxda ee qiimaha ah ee meeshaas waa la soo celiyey; haddii kale, xisaabiye interpolates linearly u dhexeeya laba qiimaha deriska ah. Tani waa habka ka mid ah (PERCENTILE.INC).
Waa maxay farqiga u dhexeeya boqolkiiba iyo quartile?
Quartiles waa kaliya boqolkiiba gaar ah oo kala qaybiya xogta afar qaybood oo isku mid ah: quartile koowaad waa boqolkiiba 25aad, kii labaad waa 50aad (midka dhexe) iyo saddexaad waa boqolkiiba 75aad.
Waa maxay kala duwanaanta interquartile?
Qaabkan interquartile (IQR) waa saddexaad quartile ka yar kii ugu horeeyay - da'da dhexe 50% ee xogta. Sababtoo ah waxay ka warqabaan afarta ugu sarreeya iyo hoostiisa waa mid aad u xoog badan oo ku faafay iyo waxaa badanaa loo isticmaalaa in ay calaamadiyaan outliers.
Maxaa ka dhigan yahay 90th percentile?
Waa qiimaha hoos ku qoran oo 90% ee xogta ku yaalla, sidaas darteed kaliya 10% oo ka mid ah aragtida waa ka sareeya. Score at 90th percentile on imtixaanka macnaheedu waa inaad ka wanaagsan ka samaysay oo ku saabsan 90% ee kale imtixaanka-qaadayaasha.
Ma 50th boqolkiiba waa la mid sida dhexdhexaadka ah?
Haa. The 50th boqolkiiba kala qaybiya xogta si ay u kala badh qiimaha hoos u dhaca, taas oo si toos ah u qeexidda ee dhexdhexaadka ah.
Maxaa ka dhigaya qalab kala duwan siin kartaa boqolkiiba yar oo kala duwan?
Waxaa jira dhowr macnaheedu waa boqolkiiba la aqbali karo. Kalkulatorkan isticmaalaa inta lagu jiro line interpolation (PERCENTILE.INC); habka gaar ah (PERCENTILE.EXC) iyo habka ugu dhow-rank meel boqolkiiba si yar oo kala duwan, sidaas daraaddeed natiijooyinka waxay kala duwanaan karaan wax yar oo ka mid ah qalabka, gaar ahaan ku saabsan set data yar.
API — isticmaal xisaabinta ka code
Wici xisaabinta sida free JSON endpoint - key ma loo baahan yahay. Dib u soo dir qiimaha goobta hoos ku qoran sida parameters su'aal ama JSON. Wax kasta oo aad ka maqan tahay isticmaalaa default la mid ah ee boggani waa hore loo buuxiyey la; parameter aan la aqoon waa 400, marnaba ma aha zero maqan. Akhri dhammaan API xuquuqda →
