Ko nga pātai e pā ana
He aha te tikanga o te pūkete z o te 2?
Ko te tikanga o tētahi pūtātau z o te 2 ko te uara e rua ngā rerekētanga paerewa i runga ake i te tauwaenga. I raro i tētahi tuaritanga pūnoa, tata ki te 97.7% o ngā uara e tū ana i raro i a ia, nō reira he uara tino nui, tino nui.
Ka āhei te pūkete z ki te tōraro?
He. Ko te tikanga anake o tētahi pūkete z tōraro ko te uara i raro iho i te tauwaenga. Ko tētahi pūkete z o −1.5, hei tauira, ko tētahi me te haurua o ngā rerekētanga paerewa i raro i te tauwaenga.
He pēhea te tatau i tētahi pūkete z?
Whakawhāiti i te tauwaenga mai i tō tātou uara me te whakawehenga mā te rerekētanga paerewa: z = (x − μ) / σ. Mō x = 85, μ = 70 me te σ = 10 ko te pūkete z (85 − 70) ÷ 10 = 1.5.
He pēhea te pātahitanga o te pūkete z ki tētahi ōrautanga?
Ka tahuri te pūtātau z ki tētahi ōrautanga mā te tuaritanga pūnoa-taurite, e hoatu ana i te ōrautanga o ngā uara i raro i a ia. Ko te pūtātau z o te 0 te ōrautanga 50, +1 tata ki te 84 me te −1 tata ki te 16.
He aha te whakaarotia he pūkete z tiketike, āhua kore rānei?
Nā te ture pūnoa, ko ngā pūkete z i tua atu i te ±2 he āhua kore, ā, i tua atu i te ±3 he āhua kore, nā te mea tata ki te 95% o te tuaritanga pūnoa e noho ana i roto i ngā whakarerekētanga paerewa e rua o te tauwaenga me te 99.7% i roto i te toru.
Me hiahiatia anei e au he tuaritanga pūnoa hei whakamahi i tētahi pūkete z?
Ka taea e koe te whakawhāiti i tētahi uara ki te tātai z, ahakoa te hanga, engari ko ngā ōrautanga me ngā tūponotanga o te kōaro e pūrongotia ana e tēnei utauta e whakaaro ana i te raraunga e whai ana i tētahi tuaritanga pūnoa. Mō ngā raraunga pūnoa-kore, ko ēnei tūponotanga e tata ana anake.
