Perhaps you should try some spelling variations:
statisties » statistiques, statistikers, statistikens
statistiek » statistik, statistiken, statistic
statistiker » statistiken, statistik, statistischer
statistica » statistical, statistic, statistician

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (statistics OR (((statisties OR statistiek) OR statistiker) OR statistica)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(statistics or (((statisties OR statistiek) or statistiker) or statistica))".
• Adding a wildcard symbol may retrieve word variants: (statistics or (((statisties OR statistiek) or statistiker) or statistica))*.
