The intended generic learning outcomes Students who successfully complete this module will: a) have begun to develop a logical, mathematical approach to solving problems; b) have enhanced their ability to work with relatively little guidance; Revision March 2014 1 UNIVERSITY OF KENT c) have gained organisational and study skills; d) be able to use information technology for data analysis and presentation. On successful completion of the module, students will also have improved their key skills in written communication, numeracy, computing and problem solving. 13.

Learning and Teaching Methods, including the nature and number of contact hours and the total study hours which will be expected of students, and how these relate to achievement of the intended module learning outcomes. Number of contact hours: 48, consisting of 36 lectures, 2 formal computing sessions and 10 exercise classes. Number of independent learning hours: 102. Revision March 2014 2 UNIVERSITY OF KENT Total study hours: 150. The lectures introduce the students to the basic concepts of probability and statistics. The material is related to real data at every stage and MINITAB is used to provide statistical computing facilities for all the material studied. Probability, data description and data summarisation techniques are studied, together with the main methods of statistical inference. Lectures contain numerous worked examples to illustrate the theoretical techniques and concepts in the curriculum. They address subject specific learning outcomes 11(a)-(d),(f),(g) and generic learning outcomes 12(a). The exercise sheets, which students are expected to attempt, aim to reinforce the lecture material, in addition to giving students practice in the various statistical techniques. In addition to the exercise sheets, students also work on several practical problems for which they need to use MINITAB. These practical problems are intended to give further reinforcement of the technical material, as well as illustrating how statistics is used in practice. Regular exercise classes are held during which students work on specified exercises with the module lecturers and other staff on hand to help with any problems. This provides each student with one-toone help when needed. Students work through worksheets which demonstrate how the statistical techniques introduced in the module can be implemented in MINITAB. The exercise classes and computing sessions address subject specific learning outcomes 11(a)-(g) and generic learning outcomes 12(a)-(d). 16. Assessment methods and how these relate to testing achievement of the intended module learning outcomes The module will be assessed by examination (90%) and coursework (10%). Coursework: Exercises will be given on individual components of the syllabus, to be worked on during the exercise classes with the module lecturers and other staff on hand to help with any problems and completed outside contact hours. The exercises consist of questions requiring mathematical manipulations and solution to numerical problems. Required answers will vary in length. The exercises assess subject specific learning outcomes 11(a)-(g) and generic learning outcomes 12(a)(d). Examination: One 2-hour written exam in the Summer term. The examination paper will consist of theoretical, manipulative and numerical problems requiring answers of varying length, testing subject specific learning outcomes 11(a)-(d),(f),(g) and generic learning outcomes 12(a)-(c). 17. Implications for learning resources, including staff, library, IT and space This module has been developed from existing modules and there are no further resource implications. 18. The School recognises and has embedded the expectations of current disability equality legislation, and supports students with a declared disability or special educational need in its teaching. Within this module we will make reasonable adjustments wherever necessary, including additional or substitute materials, teaching modes or assessment methods for students who have declared and discussed their learning support needs. Arrangements for students with declared disabilities will be made on an individual basis, in consultation with the University’s disability/dyslexia support service, and specialist support will be provided where needed. 19.
