Ko nga pātai e pā ana
He pēhea te pātahitanga o te tāupetanga ki te whakarerekētanga paerewa?
Ko te rerekētanga paerewa te pūtake tapawhā o te rerekētanga, ko te rerekētanga i roto i ngā wae tapawhā (hei tauira, ngā tāuru tapawhā), i te wā e hoki ana te rerekētanga paerewa ki ngā wae taketake, kia whakaahuatia ai e ngā mea e rua i ngā wā katoa te rerekētanga ōrite.
I te wā e whakamahia ai e au te n ki te n − 1?
Whakawehe e n − 1 ina he tauira tō tātau raraunga hei whakatau i tētahi iwi whānui ake; Whakawehe e n ina tohu tō tātau raraunga i te iwi whānui katoa e hiahiatia ana e koe.
He aha te rerekētanga i roto i ngā wae tapawhā?
Nā te mea ka tapawhā ia neke i mua i te whakawaenga, ka mau te hua ki te tapawhā o te wae taketake — ngā tāuru tapawhā, ngā inihi tapawhā, me ētahi atu mea. Ka āhei te tāupetanga ki te whakamārama hāngai, nō reira ko tōna pūtake tapawhā, te neke paerewa, e pūrongotia ana i te taha o ia.
Ka āhei te tāupetanga ki te tōraro?
Kāore. He tau tōpū o ngā tau tapawhā, nō reira ko te kore, tōrunga rānei i ngā wā katoa. Ko te tikanga o te rerekētanga o te kore, ko te tikanga he ōrite ia uara i roto i te tautuhi.
He aha te rerekētanga i waenganui i te tāupetanga me te whakarerekētanga paerewa?
E whakaahua ana rātau i te tuaritanga ōrite engari i runga i ngā tauine rerekē: ko te rerekētanga te rerekētanga tapawhā, ā, ko te rerekētanga paerewa ko tōna pūtake tapawhā, ki ngā wae taketake. Mēnā he 25 te rerekētanga, ko te rerekētanga paerewa ko te 5.
He pēhea te whakamahinga o te tāupetanga i roto i te tātaritanga tūturu?
Ko te tāupetanga e whakatū ana i te mōrearea i roto i te pūtea moni, i te hiko tohu i roto i te pūkaha me te F-tautau i roto i te ANOVA, i reira ka whakatauritetia te tāupetanga i waenganui i ngā rōpū ki te tāupetanga i roto i a rātou hei whakatau mēnā he rerekē te tikanga o te rōpū.
