All scientific investigation deals with building models for reality. The models will necessarily be simplifications of reality, and so the actual observations we do, i.e., the data we have, will contain variability not captured in the model. When our data are numbers, like counts or measurements, statistics is an indispensable tool for dealing with the variability in a scientific way, so that conclusions about the simplified models can be drawn in spite of the extra variability in the data. When the data is the result of an experiment, the design of the experiment, i.e., how it is performed, determines how firm conclusions can be drawn about the models, in spite of the variability in the data. Good experimental design is essential for a good scientific experiment; without it, a lot of work can be wasted.
The course is given for masters students from a number of different fields within the natural sciences, and we aim to reflect some of their different subject matter in the course. However, the principles of statistical analysis and experimental design are generally the same. We will focus on ideas and methods that should be useful in many masters-projects, as well as in later scientific investigations. The students' differeing interests and backgrounds in statistics will be reflected in individual or group-work on a miniproject.
The course gives 7.5 hp.
