Course abstract

The aim of the course is to deal with probability, laws of probability, distributions, statistical data, confidence intervals and hypothesis testing, linear correlation and linear regression. The study course is intended to acquire the mathematical knowledge and practical skills needed to study future special subjects, as well as to acquire skills for applying math techniques to study different problems related to Engineering science and related fields. During the course, students acquire skills in working with appropriate application software, such as “MS Excel”, “Matlab”.

Learning outcomes and their assessment

Upon successful completion of this course:
1. Knowledge - students are able to manage and demonstrate knowledge and critical understanding of probability, laws of probability, distributions, statistical data, confidence intervals and hypothesis testing, linear correlation and linear regression. Students manage the application of the acquired topics in practical examples related to the specialty of the Engineering science and related fields – tests.
2. Skillis - students are able to show understanding of the corresponding concept and regularities, to perform necessary calculations and operations. Students are able to use appropriate software for calculations – laboratory works.

3. Competence - working in a group or doing work independently, student is able to apply the mathematical calculations corresponding to the specialty problem situation, to make a professional assessment and interpretation of the intermediate result of the calculations and the final results – independent works.

Assessment: Exam.

Description of the organization and tasks of students’ independent work

In writing form and by using the appropriate software, the following independent work must be completed (all tasks are executed correctly) at times specified by the teaching staff:
Independent work 1. Definitions of probability. Laws of probability
Independent work 2. Bernoulli trials. Total probability. Bayes’ formula
Independent work 3. Discrete variables. Distributions
Independent work 4. Continuous variables. Distributions
Independent work 5. Mean, median, mode and standard deviation. Presentation of statistical data
Independent work 6. Confidence intervals
Independent work 7. Hypothesis testing

Independent work 8. Correlation and regression

Criteria for Evaluating Learning Outcomes

The student can receive the accumulative exam if:
1. all independent works are completed at times specified by the teaching staff;
2. during the semester each test score is at least 4.
Failed tests can be repeated.
The student may overwrite unsuccessfully written test work during the study process, at times specified by the teaching staff. The student can rewrite the last test in the 1st week of the individual study and examination period at the time indicated by the teaching staff.
The accumulative exam mark is
- 90% of the average mark of all tests
- 10% for completed independent works.

The written exam can be arranged at the time indicated by the teaching staff, if all the independent works are defended (all tasks are performed correctly).
