Objective

The student realizes the importance of the measurement uncertainty, unavoidable in every measurement, and is able to take that into account in decision making. The student is able to visualize and interpret statistical data. The student knows confidence intervals, statistical tests, and regression analysis, and can apply them in solving typical simple applications of his or her own field.
The student masters the basics of statistical design of experiments (DOE), and is able to design efficient series of experiments in research and development projects. The student is able to analyze results obtained from designed experiments in order to meet with the objectives of quality control, optimization or of designing systems.

Content

1. The concept and the basic laws of probability, and random variables and their most common distributions.
2. Measurement uncertainty and propagation of errors.
3. Visualization of statistical data and basic statistics.
4. Confidence intervals and statistical tests, and their applications in statistical inference.
5. Regression analysis and applications in student’s own filed of specialization.
6. Basic concepts of DOE; model and variable types.
7. The most common designs related to qualitative and quantitative variables.
8. Analyzing experimental results using analysis of variance or regression analysis.
9. Experimental optimization and response surfaces (the Box-Wilson strategy).
10. Visualising the results of statistical analyses by families of curves and response surfaces.
11. Using Excel or statistical software in statistical analyses and DOE.
