Perhaps you should try some spelling variations:
statisties » statistiek, statistiques, statistikers
statistiker » statistiken, statistik, statistiques
statistischer » statistische, statistischen
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 (statistiker OR statistischer)) OR statistica)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(statistics or ((statisties or (statistiker OR statistischer)) or statistica))".
• Adding a wildcard symbol may retrieve word variants: (statistics or ((statisties or (statistiker OR statistischer)) or statistica))*.
