Course detail

# Probability and Statistics I

FSI-S1PAcad. year: 2020/2021

The course makes students familiar with descriptive statistics, random events, probability, random variables and vectors, probability distributions, random sample, parameter estimation, tests of hypotheses and statistical software Statistica. Seminars include solving problems and applications related to mechanical engineering.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active participation in seminars, mastering the subject matter, passing both written exams and semester assignment acceptance.

Examination: Evaluation based on points obtained for semester assignment (0-10 points) and a test (0-90points). The exam test consists of two parts: a practical part (2 tasks from the theory of probability: probability and its properties, random variable, distribution Bi, H, Po, N and discrete random vector; 2 tasks from mathematical statistics: point and interval estimates of parameters, tests of hypotheses of distribution and parameters); a theoretical part (4 tasks related to basic notions, their properties, sense and practical use,and proofs of two theorems); evaluation: each task 0 to 15 points and each theoretical question 0 to 5 points; evaluation according to the total number of points (scoring 0 points for semestral assignment, any practical part task, any theoretical part task means failing the exam): 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).

Aims

The course objective is to make students majoring in Mathematical Engineering acquainted with methods of probability theory, descriptive and mathematical statistics, and with statistical software Statistica as well as to encourage students` stochastic way of thinking for developing mathematical models with the emphasis on engineering branches.

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

Participation in the exercise is mandatory and the teacher decides on the compensation for absences.
