Perhaps you should try some spelling variations:
statistischer » statistische, statistischen
statistiky » statistik, statistika, statistikk
statistiken » statistik, statistischen
statistiques » statistics
statistic » statistics, statistik, statistical

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: (statistischer OR ((statistiky OR (statistiken OR statistiques)) OR statistic)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(statistischer or ((statistiky or (statistiken OR statistiques)) or statistic))".
• Adding a wildcard symbol may retrieve word variants: (statistischer or ((statistiky or (statistiken OR statistiques)) or statistic))*.
