Kuverenga kunoshandisa z = (chibodzwa − 100) / 15 uye kugoverana kwakajairika kunounganidza mikana, zvichitenderedzwa kusvika kunhamba mbiri dzapashure pedesimali. Avhareji ye100 neSD ye15 ndizvo zvinowanzoshandiswa pazviyero izvi. Mabhuku emuedzo chaiwo ndiwo anosarudza mitemo yakakodzera, nzvimbo yezvibodzwa nekududzirwa kwazvo; curve yemasvomhu yakajairika haisimbisi kuti muedzo mutsva wakarurama. Neisser et al., 1996 Pearson, 2020
Percentile haisi chikamu chemibvunzo yakapindurwa zvakarurama
Percentile inoratidza nzvimbo yemunhu kana ichienzaniswa neboka rinoshandiswa sereferensi. Hairevi kuti munhu akapindura chikamu ichocho chemibvunzo zvakarurama kana kuti ane chikamu ichocho cheungwaru hwose. Nhungamiro yekushandisa miedzo inoda boka rereferensi rakakodzera uye humbowo hunotsigira kududzirwa kunodiwa kwechibodzwa. Pasina izvozvo, percentile inogona kuita seyakanyatsojeka kupfuura zvinobvumirwa nehwaro hwayo. International Test Commission, 2001
Chii chinochinja nezera?
IQ inoyerwa zvichienderana nezera: pachiyero chinowanzo shandiswa, avhareji yereferensi i100 muboka rega rega rezera. Mwana nemunhu mukuru vanogona kuwana chibodzwa chimwe chete chakagadziridzwa nezera kunyange vakapindura mibvunzo yakasiyana kana kuwana zviverengero zvakasiyana pazvibodzwa zvavo zvisina kugadziridzwa. Saka kuverenga kwemuenzaniso wakajairika hakutsananguri mashandiro ehupenyu hwose asina kugadziridzwa nezera. Neisser et al., 1996 Pearson, 2020
Mitemo yekuyera inosiyanawo zvichienderana nemuedzo, vanhu vari kuyerwa nenguva. Ongororo yaRaven inoratidza kusiyana kwemitemo yemiedzo yemamatriksi munzvimbo nenguva dzakasiyana. Chibodzwa chinobva pachishandiso chimwe hachifaniri kutorwa sokunge miedzo yose nematafura enhoroondo zvine nzira imwe chete yekuyera. Raven, 2000
Chii chinochikanganisa?
Nei zvichidiwa kungwarira zvikuru pazvibodzwa zviri kumagumo ekugoverana?
Mienzaniso midiki inoshandiswa kugadzira mitemo ine mashoko mashoma chaiwo pamusoro pezvibodzwa zvisingawanzoitiki. Saka percentile inokwezva iri kumucheto inogona kutsamira pafungidziro dzemodhi pamwe chete nezvakaonekwa. Nhungamiro yekushandisa miedzo inoda humbowo hunokodzera mhedziso iri kuitwa, uye kusava nechokwadi kuri pamushumo wechibodzwa kunopa mashoko akawanda kupfuura kubata digit yekupedzisira seyakanyatsojeka. International Test Commission, 2001 Pearson, 2020
Chibodzwa chepuzzle yemamatriksi chinotsanangura IQ yose here?
Carpenter nevamwe vanoongorora mafambiro ekufunga anoshandiswa mumamatriksi aRaven. Izvi zvinopa tsananguro yedzidziso yemhando yakakosha yemabasa, asi hazvirevi kuti chibodzwa chipi nechipi chepuzzle yakagadzirwa nemunhu chinogona kushandurwa kuva IQ yose ine mitemo yakatarwa. Tsvakurudzo yemaitiro ekushanda kwepfungwa inoyambirawo kuti hatifaniri kufunga kuti basa rega rega rinoyera chinhu chimwe chete chekugona. Carpenter et al., 1990 Hampshire et al., 2012
Zvakadini nekudzokorora muedzo uye kukanganisa pakuyera?
Ongororo inounganidza zvidzidzo zvakawanda yakawana kuti kudzokorora miedzo yekugona kufunga kunowanzowedzera zvibodzwa nenzira inodzokororwa. Saka chibodzwa chemuedzo wakadzokororwa chinogona kuratidza kujairana nemuedzo pamwe nemimwe misiyano. Tsvakurudzo yekuvimbika inowedzera kuti zvibodzwa zvemabasa nemisiyano yazvo zvinofanira kuratidza kugadzikana kwakayerwa tisati tazvitora seunhu hwemunhu. Kuratidza mamwe manhamba epercentile hakugadzirisi chero dambudziko iri. Scharfen et al., 2018 Hedge et al., 2017
Pakuongororwa kwakatosimbiswa, shandisa mushumo wacho, mitemo yezera uye nguva inoratidza kusava nechokwadi kwezvibodzwa. Pabasa repaindaneti rinoongorora chete, dudziro yemugumisiro ngairege kudarika zvinotsigirwa nekusimbiswa kwaro. Iyi mienzaniso yemasvomhu inotsanangura chiyero chinowanzoshandiswa; hairatidzi kuti munhu ari kutamba akangwara kupfuura chikamu chakati chevanhu. International Test Commission, 2001 Pearson, 2020
Musiyano unokosha uri pakunzwisisa maverengero epercentile uye kuva neumboo hunoratidza kuti chibodzwa chakati chinokodzera curve iyoyo. Zvose zvinodiwa usati waenzanisa munhu nevamwe. Neisser et al., 1996 International Test Commission, 2001
Edza muedzo wemahara une chekuita nazvo
Muedzo weIQ
Edza muedzo weIQ kuti uzive mabasa awo. Dudzira fungidziro yaunowana paindaneti uchifunga nezvemiganhu yayo yakataurwa. Tafura yepercentile iri pano inotsanangura chiyero chakajairika chemuenzaniso uye hairatidzi kuti Helibrain ine mitemo inomiririra vanhu vakasiyana-siyana.
Mibvunzo yakajairika
130 zvinoreva here kuti mhinduro dzakarurama i130%?
Kwete. Pachiyero chataurwa, iri pamusoro peavhareji nezvikamu zviviri zve standard deviation; kuverenga percentile ndeimwe nzira yakasiyana. Neisser et al., 1996
IQ ye100 iavhareji pazera rose here?
Hongu, maererano nechiyero chinogadziriswa nezera. Mashandiro asina kugadziridzwa emabasa anogona kuramba achichinja nezera. Pearson, 2020
Ndingashandisa tafura iyi pachibodzwa chipi nechipi chepaindaneti here?
Kwete. Muedzo unoda kuenzaniswa nemitemo yakakodzera uye kusimbiswa usati wadudzira zvibodzwa zvawo uchishandisa kugoverana ikoko. International Test Commission, 2001
