Oletame, et ol ZO10 ete algklasside õpetaja ja hindate oma õpilaste lugemistaset. Leiad inimese, kes loeb 50 sõna minutis. Uurite pisut ja otsustate, et nende klasside lugemissagedus on tavaliselt jaotunud keskmiselt 85 sõna minutis ja standard hälbega 20 sõna minutis. a. Millise protsentiili juures on lapse lugemistase (ümmargune lõppvastus ühe kümnendkoha täpsusega). b. Looge tavak overaga graafik, mis illustreerib probleemi. Graafiku jaoks ÄRGE koostage empiirilist reegligraafikut, vaid lisage õpilase protsentiilile vastava ala keskmine ja märk. Ressursipiirkonnas on lingitud tavajaotusgraafiku generaator. Laadige üles fail, mis sisaldab allolevat graafikut.
