Sampling ndi kusankha anthu kapena zitsanzo kuchokera lonse.Mwakutero, ndi njira yoyesera kapena kuyang'ana zonse.Pali mitundu iwiri ya sampuli: kusanja mwachisawawa ndi kusachita mwachisawawa.Yoyamba ndi kusankha zitsanzo kuchokera lonse zochokera randomization mfundo.Njirayi ilibe kugonjera ndipo ikhoza kugawidwa ngati zitsanzo zosavuta, kusanja mwadongosolo, kusanja kwamagulu ndi kusanja kwa stratified.Yotsirizirayi ndi njira yosankha zitsanzo kutengera malingaliro a wofufuza, zomwe wakumana nazo kapena chidziwitso chofunikira.
Malo ochezera a EC ali m'mizinda yopitilira 60 yadzikoli ndi South Asia.Oyang'anira apafupi atha kutumizidwa kuti adzakupatseni chithandizo chazitsanzo pamalo omwe mwapatsidwa.
Timatumiza woyang'anira kuti akatenge zitsanzo pamalo omwe kasitomala wapatsidwa, monga wogulitsa, fakitale kapena doko.Kuphatikiza apo, timanyamula zitsanzo ndikutumiza kumalo omwe tapatsidwa, zomwe zimasunga nthawi ndi ndalama zanu.Zitsanzo zidzasankhidwa motsatira miyezo yovomerezeka padziko lonse lapansi komanso zofunikira za kasitomala.
Tsimikizirani chidwi ndi kuyimira kwa zitsanzo!
Njira yogwirira ntchito yaukadaulo imawonetsetsa kuti zitsanzo zanu zitha kufika molondola komanso munthawi yake komwe mukupita.Kuyesa kwapatsamba ndikofunikira kwambiri.
