BSc. Statistics (Regular)

Overview

The programme provides instruction in statistical theory and methods, and their application to the collection, collation, presentation, analysis and dissemination of data. It is designed to provide practical training and to enhance the knowledge and skills of a statistician. In addition, the course seeks to meet the need of those who have developed an interest in the subject from several years of relevant working experience and who are desirous of acquiring further knowledge in the field. More specially, the programme seeks to equip students with the knowledge and skills to perform professional duties as statisticians, and to work more effectively with other specialists on statistical activities and programmes such as censuses, surveys, quality control and other statistically related projects and activities. The programme emphasizes the acquisition of practical and problem solving skills to enable students to relate what they learn to what is done in practice so as to enable them to ply more meaningful roles in solving current developmental problems at local, national and international levels.
