Bu hasapçy hakda
standardising, you can compare the values measured on the bell curve with the values measured on the normal distribution. The standardising calculator also shows you the percentile — the probability that a value from a normal distribution is above x — and the right-tail probability, using the standard-normal cumulative distribution calculated with an accurate error-function approximation, and it plots where x sits on the bell curve. The standardising calculator also shows you the percentile — the probability that a value from a normal distribution is above x — and the right-tail probability.Worked example: z = (x − μ) / σ.

Köp soralýan soraglar
2-niň z-nokady näme aňladýar?
2-niň bir z-baly mysal üçin baha ortaçadan iki standart sapmak manysynda. Normal paýlaşma astynda bahalaryň 97.7% ondan aşak düşýär, şuňa görä bu gaty agyr, ýokary baha.
Z-nokady menfi bolup bilermi?
Eý. Negatiw z-punktar diňe baha ortadan aşakda diýmekdir. Meselem -1.5 z-punktar ortadan bir yarym standart çykyş aşakda diýmekdir.
Men z-nokady nädip hasap etmeli?
Ortaçany nyşandan çykar we standart öçüm bilen böl: z = (x − μ) / σ. X = 85, μ = 70 we σ = 10 üçin z-score (85 − 70) ÷ 10 = 1.5
Bir z-nokady bir percentile nädip bagly?
Z-score bir percentile standart-normal kumulatif paýlaşma arkaly öwürilýär, bu ondan aşakdaky mykaddarlaryň proporsiýasyny berýär. 0-dan z-score 50-nji percentile, +1 84-nji we -1 16-njy.
Näme ýokary ýa-da gadymky z-score hasaplanýar?
Umumy düzgüne görä, ±2-den ýokary z-skorlar adaty däl we ±3-den ýokary z-skorlar az, sebäbi normal paýlamanyň 95% -i ortaça iki standart çykyş we 99,7% üçüsiniň içinde ýerleşýär.
Men z-nokady ulanmak üçin kadaly paýlaşmak gerekmi?
Siz z formula bilen her bir mykdary şaýat edip bilersiňiz şekilden gaça, emma bu esbapyň habar beren percentil we taý olaňlyklar datanyň normal paýlaşmany aşakda galdyrýar. Güçlü non-normal data üçin ol olaňlyklar diňe ýakynlaşar.
