'Oko'a ma waena o ka la'ana stratified a me ka la'ana pu'upu'u

Hoʻolauna

I ke ao nei Ma nā helu helu, he mea maʻamau ka hoʻohana ʻana i nā ʻenehana laʻana no ka loaʻa ʻana o ka ʻikepili hōʻike o kahi heluna kanaka. ʻElua mau ʻenehana maʻamau ʻo ka stratified sampling a me ka cluster sampling. Loaʻa nā mea ʻelua i kā lākou mau kikoʻī a hoʻohana ʻia i nā kūlana like ʻole. A laila, e ʻike mākou i ke ʻano o kēlā me kēia ʻenehana a me nā ʻokoʻa ma waena o lākou.

Stratified sampling

ʻO ka laʻana stratified ka mahele ʻana i ka heluna kanaka i nā ʻāpana like ʻole a i ʻole nā ​​pūʻulu liʻiliʻi, a laila hoʻohana i ke ʻano hana laʻana maʻalahi i kēlā me kēia papa. Ma kēia ala, ua hōʻoia ʻia e hōʻike ʻia kēlā me kēia stratum i ka hāpana, a hiki ke loaʻa i kahi laʻana ʻoi aku ka pololei a me ka homogeneous.

Laʻana

Inā makemake mākou e hana i kahi haʻawina e pili ana i ka makemake no nā haʻuki ma ke kūlanakauhale. Hiki iā mākou ke hoʻokaʻawale i ka heluna kanaka i nā ʻāpana like ʻole e pili ana i ka makahiki a me ke kāne. A laila, hoʻohana mākou i ka laʻana maʻalahi maʻalahi i kēlā me kēia papa e kiʻi i kahi laʻana o ka heluna kanaka holoʻokoʻa.

ʻĀpana hōʻuluʻulu

Ma ka hōʻailona puʻupuʻu, ua māhele ʻia nā ʻāpana heluna i nā pūʻulu a i ʻole nā ​​pūʻulu, a ua koho ʻia kahi helu o kēia mau pūʻulu no ke komo ʻana i ka hāpana. A laila, lawe ʻia nā ʻāpana a pau mai kēlā mau pūʻulu i koho ʻia e hana i ka laʻana. Pono kēia ʻenehana inā ʻaʻole loaʻa ka ʻikepili no kēlā me kēia kanaka i ka heluna kanaka, akā loaʻa no kēlā me kēia hui.

Laʻana

Inā makemake mākou e hana i kahi haʻawina e pili ana i ka maikaʻi o ka hoʻonaʻauao ma kahi panalāʻau. Ma kahi o ka ho'āʻo ʻana i nā haumāna, hiki iā mākou ke koho i kahi helu o nā kula ma ka panalāʻau a laila lawe i kahi laʻana o nā haumāna mai kēlā mau kula.

Nā ʻokoʻa ma waena o ka laʻana stratified a me ka cluster sampling

• Hoʻokaʻawale ka laʻana stratified i ka heluna kanaka i nā ʻāpana like ʻole, ʻoiai ʻo ka hōʻiliʻili puʻupuʻu e puʻunaue i ka heluna kanaka i mau pūʻulu a i ʻole nā ​​pūʻulu.
• Hoʻohana ʻo Stratified sampling i ke ʻano hana laʻana maʻalahi maʻalahi i kēlā me kēia stratum, ʻoiai ʻo ka cluster sampling e koho i nā hui e hoʻokomo i loko o ka hāpana.
• Hoʻohana ʻia ka laʻana stratified ke makemake ʻia e loaʻa kahi laʻana like ʻole a me ka hōʻike o kēlā me kēia stratum, ʻoiai ʻo ka cluster sampling he mea pono ke loaʻa ʻole ka ʻikepili i kēlā me kēia, akā loaʻa ma ka hui.

Hopena

ʻO ka hōʻuluʻulu manaʻo, ʻo ka stratified sampling a me ka cluster sampling he mau ʻenehana pono i ka honua o nā helu helu e kiʻi i nā laʻana hōʻike o ka heluna kanaka. Loaʻa i nā mea ʻelua a hoʻohana ʻia i nā kūlana like ʻole, no laila he mea nui e hoʻomaopopo i ke ʻano o kēlā me kēia ʻenehana a me nā ʻokoʻa ma waena o lākou.
