Men ziet ook hier dat de correlaties tussen de drie mogelijke manieren van bepalen van een gemiddelde waarde (namelijk het rekenkundig gemiddelde of de mean, (Ps-Ns)/(Ps+Ns) en (Pc-Nc)/(Pc+Nc)) heel hoog zijn. Hieruit kan men dus concluderen dat deze onderling inwisselbaar zijn en dat men kan werken met het rekenkundig gemiddelde (mean). Dit impliceert ook dat men de resultaten kan beschouwen als getallen waarmee men kan rekenen.
