Ikhaltyhuleyitha: Bala ubuncinci beSampula yoPhando lwakho

Isikali sokubala esikwi-Intanethi ukubala ubungakanani beSampula kuPhando

Ukuphuhlisa isaveyi kunye nokuqinisekisa ukuba unempendulo evakalayo onokuthi useke izigqibo zakho zeshishini kuyo kufuna ulwazi oluthile. Okokuqala, kuya kufuneka uqinisekise ukuba imibuzo yakho ibuzwa ngendlela engathathi cala kwimpendulo. Okwesibini, kuya kufuneka uqinisekise ukuba uphonononge abantu aboneleyo ukuze ufumane iziphumo ezichanekileyo.

Awudingi ukubuza wonke umntu, oku kunokuba nzima kwaye kubize kakhulu. Iinkampani zophando kwimakethi zisebenzela ukufikelela kwinqanaba eliphezulu lokuzithemba, umda ophantsi wempazamo ngelixa ufikelela kubuncinci bobungakanani babamkeli obuyimfuneko. Oku kwaziwa njengeyakho ubungakanani besampulu. Ungu isampulu Ipesenti ethile yabantu bebonke enokufumana iziphumo ezibonelela ngenqanaba ntembelo ukuqinisekisa iziphumo. Sebenzisa ifomula eyamkelweyo ngokubanzi, unokumisela esisemthethweni ubungakanani besampulu ezakubonisa uluntu luphela.

Bala ubungakanani beSampulu yeSaveyi yakho

Isebenza njani iSampulu?

Ifomula yokufumanisa ubuncinci beSampulu

Ifomula yokujonga ubungakanani besampulu yesampulu eyimfuneko kubemi abanikiweyo imi ngolu hlobo lulandelayo:

S = \ frac {\ frac {z ^ 2 \ times p \ left (1-p \ right)} {e ^ 2}} {1+ \ left (\ frac {z ^ 2 \ times p \ left (1-) p \ ekunene)} {e ^ 2N} \ ekunene)}

phi:

  • S = Ubuncinci besampulu yesampulu ekufuneka uyijongile unike igalelo lakho.
  • N = Inani elipheleleyo labemi. Obu bubungakanani becandelo okanye inani labantu onqwenela ukulivavanya.
  • e = Umda wempazamo. Nanini na xa usampula inani labemi, kuya kubakho umda wempazamo kwiziphumo.
  • z = Ungazithemba kangakanani ukuba abemi banokukhetha impendulo kuluhlu oluthile. Ipesenti yokuzithemba iguqulela kumanqaku e-z, inani lokutenxa okusemgangathweni kwinxalenye enikiweyo ikude nentsingiselo.
  • p = Ukuphambuka okumiselweyo (kule meko yi-0.5%).
