Isibali se-percentile ye-IQ
Faka amaphuzu e-IQ ukuze ubone i-percentile yawo, ukuthi ayivelakancane kangakanani, nokulingana kwawo kwezinye izikali ze-IQ.
I-percentile
84.1
Ngaphezu kwama-84.1% abantu
Ngaphezu kwesilinganiso
Cishe umuntu oyedwa kwabangu-6 uthola amaphuzu aphezulu kangaka noma ngaphezulu
Ithebula le-IQ ne-percentile (SD 15)
| IQ | I-percentile |
|---|---|
| 70 | 2.28 |
| 75 | 4.78 |
| 80 | 9.12 |
| 85 | 15.87 |
| 90 | 25.25 |
| 95 | 36.94 |
| 100 | 50 |

Isibali sisebenza kanjani
Amaphuzu e-IQ alandela ukusabalala okujwayelekile okunesilinganiso esingu-100. Isibali siguqula amaphuzu akho abe yi-z-score — ukuthi angakanani ukuchezuka okujwayelekile ukusuka ku-100 — bese kuba yingxenye yabantu abangaphansi kwawo.
Umphumela uyi-percentile efanayo noma yisiphi isivivinyo se-IQ esisebenzisa isikali esifanayo esingayibika.
Kungani izikali zihlukile
Akuzona zonke izivivinyo ezisebenzisa ukuchezuka okujwayelekile okufanayo. Amaphuzu angu-132 esikalini se-SD 16 acishe afane no-130 esikalini esivamile se-SD 15, futhi u-148 esikalini se-Cattell (SD 24) naye ucishe abe ngu-130.
Njalo hlola ukuthi amaphuzu asebenzisa siphi isikali ngaphambi kokuwaqhathanisa — ikakhulukazi ezidingweni zezinhlangano ze-IQ ephezulu, ezivame ukunikezwa njenge-percentile (kaningi eyama-98).
Imikhawulo evamile
- 100: isilinganiso — i-percentile yama-50.
- 115: ukuchezuka okujwayelekile okukodwa ngaphezu kwesilinganiso — cishe i-percentile yama-84.
- 130: ukuchezuka okujwayelekile okubili ngaphezu kwesilinganiso — cishe i-percentile yama-98.
- 145: ukuchezuka okujwayelekile okuthathu ngaphezu kwesilinganiso — cishe umuntu oyedwa kwabangu-740.
