Wij hebben een programma ontwikkeld dat voor u bij een gekend gemiddelde en een gekende standaarddeviatie van een ruwe score de volgende omgezette scores aangeeft:

Percentielscore
z-score
T-score
IQ-Eguivalent
de NCE-score
De CEEB-score
de AGCT-score

Neem met ons contact op en we maken uw berekeningen. Contact

Er bestaat een Percentiel naar Z-score-calculator en een Z-score naar Percentiel-calculator, die we wel handig vinden.

IQ Percentile and Rarity Chart

These are IQs, their percentiles, and rarity on a 15 SD (e.g. Wechsler) and 16 SD (e.g. Stanford-Binet) scale. They were calculated using the NORMDIST function in Excel. The number of decimal places for the rarity was varied in the hope it might be useful. You can see why presently nobody should be able to get a deviation IQ higher than 195 (or 201 on the 16 SD scale). There are not enough people in the world to 'beat'. Note that rarities given are of people that have a certain IQ or higher. Some people might find it more useful to know the rarity of people that have a certain IQ or lower. In that case use this example as a guide: If you want to know how many people have IQs of 84 or lower, look at the rarity of people that have an IQ of 116 or higher. (100 - 84 = 16. 100 + 16 = 116).

Normen: decielen, stanine en normklassen

De waarden van de decielgrenzen worden dus per normtabel op basis van het gemiddelde en de standaarddeviatie berekend en in het lijstbestand opgenomen. Het berekenen van de decielgrenzen heeft als belangrijkste beperking dat er geen rekening gehouden wordt met de scheefheid van de verdeling.

Bij de stanine (afkorting van "standard nine") worden de scores van de normgroep in negen klassen verdeeld. Dit gebeurt zodanig dat de stanine nagenoeg een standaardverdeling heeft met een gemiddelde van 5 en een standaarddeviatie van 2. Onderstaande tabel geeft de grootte van de stanineklassen en de vertaalslag naar gangbare normklassen (zie 4.)

Guiford's C-schaal (1965) is een uitbreiding van de stanine schaal die gevoeliger is aan de uiteinden van de schaal.

De Tscore is een normscore met gemiddelde 50 en sd 10. Voor interpretatie worden de grensen gehanteerd van gem.+/-1*sd, gem+/-2*sd en gem.+/-3*sd
