Statistical data analysis is an integral part of many areas of daily life. This ranges from survey research and prospective clinical studies to analyzes of latent relationships in very large databases (data mining).

Often and increasingly, percentages are used as arguments and relevant data is presented that does not always meet the criteria of a profound and reliable data analysis. Simple manual mistakes are made here again and again.

Bortz and Schuster (2010) give a good and easily understandable introduction; Eid et al. (2011) with the qualification as a standard work in many scientific disciplines.
