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

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