Module Title:   Statistics (Discrete and Continuous)

Module Credit:   20

Module Code:   CM-0123L

Teaching Period:   Semester 1

Module Occurrence:   A

Module Level:   FHEQ Level 4

Provider:   Computer Science

Related Department/Subject Area:   School of Computing, Informatics and Media (Mathematics)

Principal Co-ordinator:   Dr A Csenki

Prerequisite(s):   None

Corequisite(s):   None

Aims:
To present an introduction to the principle of randomness through event theory, random samples and discrete variables. To extend the concepts to continuous random variables, estimation and sampling, and elementary statistical inference.

Learning Teaching & Assessment Strategy:
The basic theory and illustrative examples are presented and developed in formal lectures. Complementary tailor-made example sheets are provided. These are discussed, and assistance with their solution is provided in tutorials, either on a one-to-one basis or as a staff or student-led group, as appropriate.

Formative assessment assignments encourage the ongoing digestion of the material, with the extent of the cumulative knowledge and skills acquired assessed through two coursework assignments and a formal examination.
