The statistics are concerned with the extraction and evaluation of quantitative information. Statistical methods explain regularities in certain mass phenomena, but otherwise can not be defined for individual events. Any statistical statement is subject to a assessable uncertainty. We look forward to questions and comments on the talk page.
