COURSE DESCRIPTION

Course objectives

Introduce students to the importance of the use of mathematical and statistical methods for processing experimental data, conduct multi-variety data, and planning experiments. Allow them to work on computers and familiar with standard software packages (MS Excel, Wolfram Mathematica, MatLab, Statistica).

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

1. Define the data distribution.
2. Apply second statistical hypothesis tests in chemistry.
3. Use third method of exploration data on real chemical systems.
4. Know the fourth design an experimental procedure.
5. Put the methods of modeling and optimization, and extract the useful information to know.
6. Know calibrate the analytical system, process measurement signal in order to obtain useful information

Student responsibilities

Screening student work (name the proportion of ECTS credits for eachactivity so that the total number of ECTS credits is equal to the ECTS value of the course):

 Class attendance 0.5 Research 0 Practical training 1.0 Experimental work 0 Report 0 Essay 0 Seminar essay 1.5 Tests 0 Oral exam 1 Written exam 1 Project 1

Grading and evaluating student work in class and at the final exam

The entire examination can be applied over the two partial test of theoretical and seminar materials during the semester. Passing threshold is 60%. Each colloquium in the assessment accounts for 50%. Lectures presence of 80 to 100% is 10% marks. The examination periods there is a written, oral and written and oral examination. Passing threshold is 60%. Passing one partial test from any part (previous activity) is valid throughout the current academic year. Written exam has a share of 30% of oral and written with 60% and 10% verbal. Students who did not pass the exam by the partial tests take the exam through written, oral and written-oral examination in the regular examination periods. Passing threshold is 60% and the examination form to participate in the assessment with 50%.
Rating: 60% -69% - satisfactory, 70% -79% - a good 80% -89% -very good, 90% -100% - excellent.
