The course provides an introduction to Design of Experiments in the field of engineering. The concept of measurement is presented as a key method for information acquisition which together with correct interpretation allow understanding of not only engineering phenomena. Provided is an introduction to applied mathematical statistic and up-to-date data analysis with computer support. During exercises students master design of effective experiments and get skilled with MATLAB environment especialy with tools for data analysis.
