Mayelana nalolu hlelo lokusebenza

Yenza ukuhlolwa kwe-hypothesis ngokusebenzisa i-calculator yethu yokubaluleka ebalulekile.
I-Critical value calculator, ithuluzi lezandla lezibalo, linquma inani le-t ne-z-value ngokuchofoza. I-calculator eyodwa ye-t-value kanye ne-z-value wokubala iyatholakala esitolo sokudlala okwamanje, azanele izidingo zabafundi. Kodwa-ke, kulesi sibalo sokubala esibucayi ungabala womabili amanani abucayi.
Manje usungasusa umkhuba odinisayo wokubuka ngamakhulu wamatafula we-t- no-z-value ngoba isibali sokubala esibucayi sibabala ngokushesha.
Ungazenza kanjani izibalo:
Bala inani le-t
• Cacisa ileveli yokubaluleka ebhokisini elinikeziwe.
• Khetha amadigri enkululeko.
• Bala inani le-t
Bala inani le-z
• Faka ileveli yokubaluleka ebhokisini lokufaka.
• ukubala inani le-p
Ungasetha kabusha isibali sokubala esibucayi ngokucindezela inkinobho ethi “setha kabusha”.

Izincazelo eziyisisekelo:
• Inani elibalulekile: Liyinani elisikiwe legrafu elenziwe i-static yokuhlola futhi libonisa isifunda lapho i-test static ingekho khona. Inani elibucayi lincike ezingeni lokubaluleka. T utshela ukuthi ukwamukela ukulahla i-null-hypothesis.
• Izinga lokubaluleka: Izinga lokubaluleka noma ukubaluleka kwezibalo kunquma ukuthi umehluko kubantu awukwazi ukuhlanganiswa nethuba kuphela.
• I-null hypothesis: I-hypothesis engachazi mehluko phakathi kwemininingwane emibili. Futhi uma kukhona umehluko obonakalayo ubonakala ngengozi kuphela. Isifinyeziwe njengo (Ho).
• Inani le-T: Umehluko obaliwe kugrafu ngokuhlobene nedatha.
• Inani le-Z: Liyindawo yamaphoyinti okusikwa ngaphansi kokusatshalaliswa okujwayelekile kwemininingwane.
