Probability and Statistics

Course Description

The concept of the probability space and the random variables is introduced. The basic discrete and continuous random variables are analized, as well as random vectors. The foundations of the sample theory, the estimation theory and the statistical tests are given. Stochastic processes are discussed, in particular Poisson and similar processes.

General Competencies

Students are trained to calculate the probabilities of events, characteristics of events related to concrete examples and defined random variables. For given samples of empiric data student are capable to estimate the different parameters of various distributions and test different kind of hypotheses. Students are introduced to basics of stochastic processes.

Learning Outcomes

  1. compute the probability of given event and the characteristic related to concrete example.
  2. recognize a characteristic distribution.
  3. manipulate with discrete and continuous random variables.
  4. manipulate with discrete and continuous random vectors.
  5. estimate the parameters of various distributions.
  6. apply testing hypotheses using the learned statistical tests.

Forms of Teaching

Lectures

Lectures are organized through two cycles. The first cycle consists of 7 weeks of classes and mid-term exam, a second cycle of 6 weeks of classes and final exam. Classes are conducted through a total of 15 weeks with a weekly load of 4 hours.

Exams

Mid-term exam in the 8th week of classes and final exam in the 15th week of classes.

Exercises

The brief assessments will be held during the auditory exercises (up to 1 hour per week).

Consultations

Consultations are held one hour weekly according to arrangement with students.

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Threshold Percent of Grade
Quizzes 0 % 20 % 0 % 20 %
Mid Term Exam: Written 0 % 40 % 0 %
Final Exam: Written 0 % 40 %
Exam: Written 0 % 80 %
Comment:

The scores achieved on short tests will be transferred to the score of the exam only in the case when it is in the interest of the student.
