Learning outcomes:
After successfully completing this module, students will be able to use suitable methods of data analysis to gain knowledge for decision-making in practical questions. Students will become familiar with important data analysis procedures. They will be familiar with different types of characteristics (e. g. nominal, ordinal, metric) and can preprocess data appropriately (e. g. by normalization or standardization). Students will be able to select appropriate decision-making procedures (e.g. regression or classification) for specific problems. They will be able to implement the procedures they have learned in a suitable programming language (e. g. Python or R) or use an available implementation. Students will be able to systematically determine the parameters of the applied methods on the basis of available data and critically assess the quality of their results. They will be able to prepare the knowledge gained from the data appropriately (e. g. in the form of visualization) in order to make it understandable for a technically trained or non-technically trained audience (e. g. decision-makers in the company).
