### Course Description

Course Description

This course is designed to familiarize students with basic concepts in statistics. The contents include the data analysis techniques, the study of probability and measures of uncertainty, discrete and continuous distribution, estimation, hypothesis testing, correlation and regression analysis, and the application of other relevant modern statistical methods for decision-making with emphasis on business application. Throughout the course students will utilize the technology to gather, organize, and summarize the data into meaningful information. Further, students will apply the software to draw inferences from the data so that appropriate decisions can be recommended.
