download (6)SIT 101 Business Statistics

Business statistics is the science of good decision making in the face of uncertainty and is used in many disciplines such as financial analysis, econometrics, auditing, production and operations including services improvement, and marketing research.

 

Course Objectives

The aim of the course is to develop competency and ability to use statistical techniques in conducting research and project work. The emphasis of the course is more on interpretation of results and understanding of the strengths and limitations of different statistical measures. 

Course Description

This course has a business focus. The course covers fundamentals of descriptive and inferential statistical techniques. The contents include data summaries and descriptive statistics; introduction to a statistical computer package; Probability: distributions, expectation, variance, covariance, statistical inference of univariateand bivariate data for hypothesis testing. 

Course Outcomes

By the end of this course students would be able tounderstand and use the descriptive and inferential statistical tools used in business decision making ,select  an appropriate graph to describe a distribution,calculate and interpret the shape, center and spread of a distribution,understand the problem of inference when working with the results from random samples, andanalyze the data using excel.
