Course detail
Mathematics IV
FSI-4M-A Acad. year: 2025/2026 Summer semester
The course makes students familiar with descriptive statistics, random events, probability, random variables and vectors, probability distributions, random sample, parameters estimation, tests of hypotheses, and linear regression analysis. Seminars include solving problems and applications related to mechanical engineering. PC support is dealt with in the course entitled Statistical Software, which is optional.

Rudiments of the differential and integral calculus.
Rules for evaluation and completion of the course
Seminar credit conditions:
- active attendance in practices
- sufficient or better of written exam
- admission of semester assignment.
Examination (written form) consists of two parts:
- a practical part – tasks from the covered topics. Total 0 to 80 points (with own summary of formulas)
- a theoretical part – 4 tasks related to basic notions, (their properties, sense and practical use); each theoretical question 0 to 5 points.
Evaluation: each task 0 to 20 points evaluation according to the total number of points from practical and theoretical part: excellent (90 – 100 points), very good (80 – 89 points), good (70 – 79 points), satisfactory (60 – 69 points), sufficient (50 – 59 points), failed (0 – 49 points).
Attendance at seminars is controlled and the teacher decides on the compensation for absences.
Aims
The course objective is to make students acquainted with basic notions, methods and progresses of probability theory, descriptive statistics and mathematical statistics as well as with the development of students` stochastic way of thinking for modelling a real phenomenon and processes in engineering branches.
Students obtain the needed knowledge of the probability theory, descriptive statistics and mathematical statistics, which will enable them to understand and apply stochastic models of technical phenomena based upon these methods.
