Bufakazi lobubalulekile netinombolo
| Likolo lelingumfanekiso | Tichezuko letijwayelekile letingetulu kwa-100 | I-percentile yemodeli lejwayelekile |
|---|---|---|
| 100 | 0 | 50.00 |
| 115 | 1 | 84.13 |
| 130 | 2 | 97.72 |
| 145 | 3 | 99.87 |
Lesibalo sisebentisa z = (score − 100) / 15 kanye nekusabalala lokujwayelekile lokuhlanganako, bese sizungezisa sibe netindzawo letimbili ngemuva kweliphuzu. Silinganiso sa-100 nekuchezuka lokujwayelekile kwa-15 kuyimigomo lejwayelekile yesikali. Tincwadzi teluhlolo lwangempela ngito letibeka timiso letifanele, emabanga etikolo nendlela yekutichaza; lijika lelijwayelekile lesibalo alifakazeli kutsi luhlolo lolusha lulungile. Neisser et al., 1996 Pearson, 2020
I-percentile ayisho emaphesenti etimphendvulo letilungile
I-percentile ikhombisa simo salomuntfu uma sicatsaniswa nelicembu lelisetjentiswa njengelireferensi. Ayisho kutsi umuntfu uphendvule kahle emaphesenti lawo emibuto noma uneliningi lelo lawo onkhe emakhono engcondvo. Imitsetfo yekusebentisa luhlolo idzinga licembu lelifanele lekucatsanisa kanye nebufakazi yendlela lokuhloswe kutsi sichazwe ngayo sikolo. Ngaphandle kwaloko, i-percentile ingabonakala icondze kakhulu kunaloko bufakazi bayo buvumela. International Test Commission, 2001
Yini leshintjako ngeminyaka?
I-IQ ilinganiswa ngekuya ngeminyaka: esikalini lesivamile, silinganiso sereferensi ngu-100 elicenjini ngalinye leminyaka. Umntfwana nemuntfu lomdzala bangatfola sikolo lesifanako lesilungiswe ngeminyaka nanobe baphendvula imibuto leyehlukene noma banemiphumela leyehlukene yekubala yekucala. Ngako-ke, tibalo temodeli lejwayelekile atichazi indlela umuntfu lenta ngayo kuyo yonkhe iminyaka ngaphandle kwekulungisa ngeminyaka. Neisser et al., 1996 Pearson, 2020
Timiso tekucatsanisa tiphindze tincike eluhlolweni, esibalweni sebantfu nasenkhatini. Kubuyeketwa kwa-Raven kukhombisa kutsi timiso tekucatsanisa temaluhlolo emaphethini etindzaweni ngetikhatsi letehlukene tiyahluka. Sikolo lesitfolwe ngelithuluzi linye akukafaneli sitsatfwe shengatsi tonkhe tinhlobo teluhlolo nawo onkhe emathebula etimiso esikhatsini lesendlulile tilinganisa ngendlela lefanako. Raven, 2000
Yini letsintsa loku?
Kungani kufanele sinake kakhulu emiphumeleni lengakavami kakhulu
Emacembu lamancane lasetjentiselwa kubeka timiso, kuba nelwati loluncane lolucondzile ngemiphumela lengakavami kakhulu. Ngako-ke, i-percentile lephakeme kakhulu ingancika nakutinkholelo temodeli, hhayi kuloko lokubonwe kuphela. Imitsetfo yekusebentisa luhlolo idzinga bufakazi lobufanele siphetfo lesentiwako, futsi kungacondza kakhulu kubona kungaciniseki kwemphumela kunekutsatsa inombolo yekugcina ngemuva kweliphuzu njengeyiqiniso leliphelele. International Test Commission, 2001 Pearson, 2020
Sikolo sendida yemaphethini singasho i-IQ yonkhe yini?
Carpenter nalabanye bahlatiya indlela yekucabanga esetjentiswa kumathebula emaphethini a-Raven. Loko kuchaza ngetindlela temcondvo umndeni lobalulekile wemisebenti, kodvwa akuniketi imvume yekuguqula noma ngusiphi sibalo sendida lesitentelwe ekhaya sibe yi-IQ yonkhe lenetimiso. Umsebenti lohlola kwakheka kwekusebenta kwengcondvo nawo uyecwayisa kutsi singacabangi kutsi wonkhe umsebenti ulinganisa intfo yinye ncamashi emakhonweni. Carpenter et al., 1990 Hampshire et al., 2012
Kutsiwani ngekuphindza luhlolo neliphutsa lekukala?
Kuhlatiya kuhlanganisa tifundvo letinyenti kutfola kutsi imiphumela yekuhlola kabusha emaluhlolweni emakhono engcondvo ivame kukhula ngendlela lefanako. Ngako-ke, umphumela weluhlolo loluphindziwe ungakhombisa kujwayela kanye naletinye tingucuko. Lwati lwekutsi luhlolo lwetsembekile yini luphindze lutsi tikolo temisebenti nemahluko kumele kucinisekiswe kutsi kuhlala kucine ngaphambi kwekutsi kutsatfwe njengebuntfu lobungaguquki bemuntfu. Kute kulungiswe nalokunye kwaloku ngekubonisa emadijithi lamanyenti e-percentile. Scharfen et al., 2018 Hedge et al., 2017
Uma usebentisa luhlolo lolwamukelekile, sebenzisa umbiko walo, timiso teminyaka kanye nelibanga lekuciniseka. Emsebentini we-inthanethi lohlolwako, chaza umphumela kuphela ngendlela bufakazi bekucinisekisa kwawo lobuvumelako. Letibonelo tesibalo tichaza sikali lesivamile; atisivumeli kutsi sitjele umdlali kutsi uhlakaniphe kunemaphesenti latsite ebantfu. International Test Commission, 2001 Pearson, 2020
Kubalulekile kuhlukanisa emkhatsini wekucondza kutsi i-percentile ibalwa kanjani kanye neba bufakazi bekutsi sikolo lesitsite sifanele sibekwe kulelo jiko. Kudzinga kokubili loku ngaphambi kwekucatsanisa umuntfu nalabanye. Neisser et al., 1996 International Test Commission, 2001
Zama luhlolo lwamahhala loluhlobene naloku
Luhlolo lwe-IQ
Zama luhlolo lwe-IQ kuze uhlole imisebenti yalo. Cabangela lesilinganiso salo se-inthanethi ngekuya ngemikhawulo lechaziwe. Lithebula lama-percentile lapha lichaza sikali lesivamile lesicatjangwako, futsi alibeki timiso letimelele imiphumela ye-Helibrain.
Imibuto lejwayelekile
Ingabe u-130 usho kutsi timphendvulo letilungile ngu-130%?
Cha. Kulesikali lesichaziwe, ungatungeletela lokuphambuka lokujwayelekile loku-2 ngetulu kwesilinganiso; kubala i-percentile ngumsebenti lowehlukile. Neisser et al., 1996
Ingabe i-IQ ya-100 isilinganiso kuyo yonkhe iminyaka?
Yebo, ngokwesikali lesivamile lesilinganiswa ngeminyaka. Umphumela wemsebenti ungachubeka ushintje ngeminyaka. Pearson, 2020
Ngingalisebentisa yini leli thebula kunoma ngusiphi sikolo se-inthanethi?
Cha. Luhlolo ludzinga timiso tekucatsanisa letifanele kanye nebufakazi bekutsi luyasebenta ngaphambi kwekutsi tikolo talo tichazwe ngaloko kusabalalisa. International Test Commission, 2001
