Knowledge of the basic chemometrics’ terms, validation parameters and methods of statistical treatment of experimental data. Practical utilization of the available software for chemometrics calculations and for processing of measured data.

Lectures

Experimental work in labs

Other activities

The aim of the lectures is to acquaint the students with the issue of the probability, statistics and data processing. Students will study how to use the validation procedures and how to evaluate correctly the measured data. The focus of the practical exercises is on the training of the computer software for chemometric calculations and other applications. Another aim of the practical courses is to help the students with the processing of their own data measured within diploma thesis and the treatment of the data obtained during other research activities.
