Je had beter de assen benoemt dan had het duidelijker geweest welke data bij welke histogram hoort.

Als je naar de Back to back histogram kijkt zie je duidelijk dat de verdeling in klasses fout gebeurd. Je had de data beter kunnen analyseren indien je aparte histogrammen had geblogd. Ik heb er één even rap voor jouw gedaan en hierin kan je beter de klasses en spreiding zien van je gegevens: http://www.freestatistics.org/blog/index.php?v=date/2008/Oct/22/t122470037213ja40jlbbwwyho.htm

Ik ga akkoord met bovenstaande feedback. Als je eenmaal je histogrammen hebt, kan je deze gaan interpreteren. Waar liggen de gemiddelden van beide zaken die je vergelijkt? Zijn de histogrammen symmetrisch? Komen ze met elkaar overeen? Zijn er volledig buitenstaande blokjes (=outliers)? enz.

Het berekenen van dit back-to-back histogram haalt niet veel uit, zelf trek je er ook geen conclusies uit en dat ik ook niet. Maar zoals hier boven al vermeld, en dat is wel een goede oplossing, is de 2 histogrammen apart gaan bekijken en zien of er veel verschillen inzitten.
