    Program : M.Phil Education/ MS-Library InformationSciences

    Course Name: Applied Statistics in Education & Library Sciences

    Course Objectives

    This course aims at introducing the students to business mathematics

    and build up a sound foundation for studying the higher mathematical subjectof quantitative techniques and operational research. The course will be avaluable guide to business students who will be supposed to apply the modernmathematical techniques to solve a number of basic decision-makingproblems which they will encounter in their daily business transactions.Throughout the course the basic mathematical principles are explained,illustrated and applied in solving different financial and other related businessproblems with suitable examples.

    Module No 1.
