5.5.2 popezera mpata heterogeneity

Mukakhala anatakasa anthu ambiri ntchito pa vuto lenileni sayansi, mupeza kuti ophunzira anu adzakhala sakanikira m'njira ziwiri zikuluzikulu: iwo zimasiyana luso lawo ndipo zimasiyana mu msinkhu wawo khama. Zimene loyamba la akatswiri ambiri chikhalidwe ndi kuti achotse otsika ophunzira khalidwe ndipo kenako amafuna kusonkhanitsa zochuluka za mfundo onse anathawa. Iyi ndi njira yolakwika kupanga ntchito misa mgwirizano.

Choyamba, palibe chifukwa kuti achotse otsika ophunzira aluso. Mu kuyitana lotseguka, otsika ophunzira aluso chifukwa palibe mavuto; zopereka zawo sizimapweteka aliyense ndipo popanda nthawi iliyonse kufufuza. Mu masovedwe anthu ndipo anagawira ntchito deta, Komano, zabwino mawonekedwe a ulamuliro khalidwe akubwera kupyola redundancy, osati mtanda mkulu nawo. Ndipotu, osati kupatulapo otsika luso ophunzira, njira yabwino ndiyo kuwathandiza kuti zopereka bwino, mmene akatswiri pa eBird mwachita.

Chachiwiri, palibe chifukwa kusonkhanitsa ndi zochuluka za mfundo aliyense. Nawo ntchito ambiri misa mgwirizano ndi amazipanga wosiyana (Sauermann and Franzoni 2015) ndi ochepa anthu zimathandiza kwambiri amati mutu mafuta -ndipo anthu ambiri zimathandiza pang'ono amati mchira wautali. Ngati mulibe deta pamutu mafuta ndi mchira wautali, inu akusiya matani mudziwe uncollected. Mwachitsanzo, ngati Wikipedia analandira 10 ndi kusintha 10 okha pa mkonzi, izo wopanda za 95% ya kusintha (Salganik and Levy 2015) . Choncho, ndi ntchito misa mgwirizano, ndi bwino popezera mpata heterogeneity osati kuyesa kuthetsa izo.
