Business Statistics MAT 1430 Syllabus

Textbook: Business Statistics, 4th edition. Norean R. Sharpe, Richard D. De Veaux, and Paul F. Velleman, (c) 2019, Pearson Education Inc.

The content detail below covers material from Chapters 1-19.  

Course Coordinator: Chelsea Romito

Catalog Course Description:
To introduce statistical concepts and methods useful in analyzing problems in all areas of business and economics.  In addition to learning the concepts, applications will be addressed in: Descriptive Statistics, Discrete and Continuous Probability Distributions, Sampling Distributions, Confidence Intervals, Hypothesis Testing, and Regression Analysis.

The purpose of this course is to provide the students with a sound conceptual and practical introduction to statistics and its applications in the business and economic fields.  Upon completion of the course, a student will be able:

  • To recognize business situations that require the use of statistical tools of analysis.
  • To select and execute the appropriate statistical tool for a specific business situation.
  • To develop critical judgment and decision-making ability through the use of quantitative tools and statistical software.
  • To address ethical issues when presenting and interpreting statistical information.

Topical Coverage:
       I.   Numerical and Graphical Summaries
       II.  Probability Distributions
       III. Methods of Inferential Statistics
       IV.  Regression and Correlation Analysis
