Te tātaitai tuaritanga noa iho
Ka kitea te kiato tūponotanga me te tūponotanga whakatōpū mō tētahi uara pūnoa.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
the standard-normal distribution, the probability density at x is equal to the cumulative probability P(X ≤ x) (the area under the curve to the left). The right-tail probability P(X ≥ x) is equal to the equivalent z-score. The probability density at x is equal to the cumulative probability P(X ≤ x) (the area under the curve to the left). The right-tail probability P(X ≥ x) is equal to the equivalent z-score. The probability density at x is equal to the standard-normal distribution.The calculator is a simple, easy-to-use tool that can be used by anyone who wants to learn how to calculate the standard-normal distribution. The calculator is a free-to-Work
Ko nga pātai e pā ana
He aha te rerekētanga i waenganui i te pdf me te cdf?
Ko te kiato tūponotanga (pd) ko te tiketike o te ānau kōaro i x; kāore i te tūponotanga i tōna ake āhua. Ko te tuaritanga whakatōpū (cdf) ko te rohe i raro i te ānau tae atu ki x, e hoatu ana i te tūponotanga o tētahi uara i te x, i raro rānei i te x.
He aha te āhua o te uara tika o te kore?
Mō tētahi tuaritanga tūturu pēnei i te pūnoa, he kore ngā pito kotahi e taea te āhei - ko ngā awhe anake e āhei ana ki te kore. Ko te take e pūrongo ana tātau i te kiato i x me te rohe whakatōpū, kaua ko P(X = x).
He aha te ture 68–95–99.7?
Mō tētahi tuaritanga pūnoa, tata ki te 68% o ngā uara kei roto i tētahi rerekētanga paerewa o te tauwaenga, 95% i roto i te rua, ā, 99.7% i roto i te toru. He huarahi tere tēnei ki te whakatau i te āhua o te uara, me te kore tatauranga i te rohe tika.
He pēhea te kimi i te tūponotanga i waenganui i ngā uara e rua?
Ka tāuru te uara i raro iho hei x me te uara tiketike hei x2; Ka hoki te tātaitai ki P(x ≤ X ≤ x2) mā te tango i te tūponotanga tapeke i te pito i raro iho mai i te pito i runga.
He aha te rerekētanga i waenganui i te tuaritanga pūnoa me te pūnoa paerewa?
Ko te pūnoa paerewa anake te tuaritanga pūnoa me te tauwaenga o te 0 me te whakarerekētanga paerewa o te 1. Ko te tahuritanga o tētahi uara ki tōna pūtāhua z e whakamahere ana ki te pūnoa paerewa, ko te āhua o te tatautanga o tēnei utauta i ngā tūponotanga mō ētahi μ me σ.
Me tika te āhua o te raraunga?
Kāore he raraunga tūturu e tika ana, engari he tino tika ngā hua ina tata te āhua o te raraunga, ā, he āhua ōrite. Mō ngā raraunga pūmau, mārō rānei, he āhua tata noa iho te āhua o te raraunga.
