### Course Objective

The basic objective of this course is to provide students an understanding of concepts of business statistics and to acquaint the students with necessary statistical and mathematical tools and techniques to be used in business decision-making processes.

### Course Description

This course comprises introduction to statistics, classification and presentation of data, measures of central tendency, measures of dispersion, Skewness, kurtosis and moments, simple correlation and regression analysis, analysis of time series, index numbers, probability, sampling and estimation, quantitative analysis, determinant and matrix.

### Learning outcomes

On the completion of this course, students will be able to:

• classify, present and analyze the business and management related
• interpret the data from the management
• apply forecasting techniques in business and management.
• use quantitative techniques in different decision making
• apply the tool for cause and effect relationship in managerial decision.
