Learning outcomes of the course unit

Student will be able to solve simple practical probability problems and to use basic statistical methods for interval estimates, testing parametric and non-parametric statistical hypotheses, and linear models.

Prerequisites

Basics of the theory of one- and more-functions (derivative, partial derivative, limit and continuous functions, graphs of functions). Calculation of definite integrals, double and triple integrals, knowledge of their basic applications.

Co-requisites

Not applicable.

Recommended optional programme components

Not applicable.

Recommended or required reading

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations - lectures, seminars.

Assesment methods and criteria linked to learning outcomes

A student will only receive credit if he or she has attended all the workshops and passes a written test with at least 50-percent success.

An exam with a pass rate of at least 50% will follow. The examination will be only a written one lasting 90 minutes and consisting of 3 practical problems to calculate and one problem with questions about the theoretical background.

Language of instruction

Czech, English

Work placements
