Perhaps you should try some spelling variations:
statistischer » statistischen, statisticsr, statisticalr
statistische » statistics, statistical
statistika » statistiska, statistikah, statistik
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 statistische) OR (statistika OR statistic)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((statistischer OR statistische) or (statistika or statistic))".
• Adding a wildcard symbol may retrieve word variants: ((statistischer OR statistische) or (statistika or statistic))*.
