| Objectives |
The students can correctly understand and interpret statistical information. Given some data, they are able to select the appropriate graphical and tabular displays as well as statistical indicators to adequately describe the (joint) distribution of the data. The students understand the principle of statistical hypothesis tests and can apply this principle, among other things, to testing the differences in proportions and mean values of samples from two different populations. Furthermore, the students can apply the method of linear regression to estimate linear causal relationships and are able to assess the quality of the linear fit. The students are aware of the importance of carefully planned experiments, especially in technical applications. They are familiar with some of the major types of experimental designs, such as factorial and fractional factorial designs, and understand their fields of application, advantages, and limitations.
