I-Calculator ye-Z-Score
Guqula inani elimnyama libe yiz-score z bese uthola i-percentile yayo.
Iziphetho zivuselelwa uma ubhala.

standardising, you can compare the values of two different scales. The standardising method is called standardization. The standardization method is a method of calculating the standard deviations of a test. The standardization method is a method of calculating the standard deviations of a test.

Imibuzo ebuzwa kaningi
Yini okusho i-z-score ye-2?
Izinga le-z le-2 lisho ukuthi ixabiso liyizinhlamvu ezimbili ezijwayelekile eziphezulu kwezinga. Ngesihlukaniso esijwayelekile, cishe i-97.7% yamaxabiso awela ngaphansi kwayo, ngakho-ke iyinani eliphakeme, eliphakeme.
Ingabe i-z-score ingabi yikho?
Yebo. Izinga le-z eli Negative lisho ukuthi inani lingaphansi kwezinga eliphakathi. Izinga le-z le -1.5, isibonelo, liyi-standard deviations eyodwa nengxenye ngaphansi kwezinga eliphakathi.
Ngiyibala kanjani i-z-score?
Khubaza umphakathi kusuka kuxabiso lakho bese uhlukanisa ngezinga elijwayelekile lokuguquka: z = (x − μ) / σ. X = 85, μ = 70 ne σ = 10 i-z-score yi (85 − 70) ÷ 10 = 1.5.
Uyini umphumela we-z ophathelene nephesentiyeli?
I-z-score iguqulwa ibe yi-percentile nge-standard-normal cumulative distribution, enikeza inhlanganisela yamaxabiso angaphansi kwayo. I-z-score ye-0 iyi-percentile ye-50th, +1 iyi-84th kanye ne-−1 iyi-16th.
Yini ethathwa njenge z-score ephakeme noma engajwayelekile?
Ngomthetho ojwayelekile we-thumb, ama-z-scores angaphezu kwe-±2 ajwayelekile futhi angaphezu kwe-±3 avame ukutholakala, njengoba cishe i-95% yokwabelana okujwayelekile ikhona ngaphakathi kwezinguquko ezimbili ezijwayelekile zesilinganiso kanye ne-99.7% ngaphakathi kwezithathu.
Ingabe ngidinga ukuhlukaniswa okujwayelekile ukusebenzisa i-z-score?
Ungabeka noma yiluphi uphawu ngefomula ye-z ngaphandle kokubheka ifomu, kodwa i-percentile ne-tail probabilities le thuluzi likhombisa ukuthi idatha ilandela ukusabalalisa okujwayelekile. Ku-data eqinile engajwayelekile, lezi zinto ziyi-approximate.
API — sebenzisa le calculator kusuka kukhodi
Nquma le kalkuli njengendawo ephelezelwa i-JSON - akukho isitshixo esidingekayo. Thumela amaxabiso endawo ngezansi njengepharamitha yombuzo noma i-JSON. Noma yini ongayishiya isebenzisa iphutha elifanayo elifakwe ngaphambili lekhasi; ipharamitha engaziwa yi-400, ayikho i-zero emnyama. Funda i-API egcwele →
