This book is written as a text book for the students of Economics and Commerce of all Indian Universities. It is expected to be equally useful for the students of BBA, MBA, PGDM, ICWA and CA. Keeping in view the difficulties faced by majority of the students of economics and commerce in learning this subject, particularly those topics statistics that require the knowledge of higher mathematics, best efforts are made to explain various concepts as simply as possible. Explanatory notes are given at many places to enable the students understand various concepts of statistics.
