Course detail

Planning and Evaluation of Experiments

FSI-TPXAcad. year: 2018/2019

The course deals with the following topics: Basic terms and tasks. Construction of a statistical model, bias correction. Orthogonal functions, tests of residuals, addition of parameters and generalisation error. Correlation, rank-test and maximal correlation, principal components. Upper limits, significance of structures at noise level. Instructive solutions of tasks with illustrative experiments.

Learning outcomes of the course unit

Students will be able to asses the significance of results obtained, the influence of their correlations, compare relevance of choice of models for description of experimental data, apply physical limits on estimate confidence intervals.


Mathematics, namely calculation of the basic statistical characteristics of the data set.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles illustrated on specific (real or simulated) examples. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

The assessment of a student is made upon his/her performance in practicals and the competence in a discussion during the colloquium (of the topics related to the solution of the final problem of the course).

Language of instruction


Work placements

Not applicable.


The aim of the course is to provide students with basic mathematical tools necessary for statistical evaluation of experimental results obtained when using other methods.

Specification of controlled education, way of implementation and compensation for absences

Attendance at practicals is obligatory and is monitored by the tutor. Absence may be compensated for by the agreement with the tutor depending on the length of absence.
