Computer-based data processing requires their users to be able to analyze complex problems. This subject is a combination of lectures and computer-based practical, whereby theory is firmly placed into practice. In contrast to classical mathematical statistics, emphasis is placed not on particular methods but on their appropriate combinations, enabling the assessment of data quality, the selection of a suitable statistical model, its verification and the interpretation of the results with respect to the goal of data analysis. The learning is centered around focusing more on conceptual understanding of key concepts, and statistical thinking, and less on formulas and calculations, which can now be left to PCs. Statistical skills enable students to intelligently collect, analyze and interpret data relevant to their decision-making.
