DSCI 245. DATA ANALYSIS FOR BUSINESS. 4 Credits.

Pre-requisites: completion of CPLA 100 and 101 or CPLA 120 or equivalent and one of the following: MATH 142, MATH 161 or MATH 200.
An introduction to decision making in the business environment using statistical and data analysis procedures. Computer software is used extensively. Written communication skills are emphasized as a means to incorporate analysis results into the decision making process. Topical coverage includes discrete and continuous probability distributions, sampling distributions, estimation and hypothesis testing.

DSCI 297. WORKSHOP, SHORT COURSE, CONFERENCE, SEMINAR. 1-5 Credits.

DSCI 299. DIRECTED STUDY. 1-15 Credits.

DSCI 346. ADVANCED DATA ANALYSIS FOR BUSINESS. 4 Credits.

Pre-requisites: completion of CPLA 100 and CPLA 101 or CPLA 120 (or equivalent) and DSCI 245 (or equivalent) and one of the following: MATH 142, MATH 161 or MATH 200.
This course offers and in-depth study of decision making in the business environment using statistical and data analysis procedures. Statistical methods used in decision making include chi-square tests, analysis of variance, correlation, simple and multiple regression, time series analysis, and forecasting. Computer software is used extensively for both analysis and presentation. Case studies or projects are used to integrate statistical methods with problem solving and communication skills.

DSCI 399. DIRECTED STUDY. 1-5 Credits.

Pre-requisites: permission of the instructor, department chair and college dean.

DSCI 445. INTRODUCTION TO BUSINESS ANALYTICS. 4 Credits.

Pre-requisites: DSCI 346 or equivalent.
Business analytics is a hybrid of information systems, applied statistics, management science, data analysis, operations research, consumer behavior, risk management and decision support. The focus of this particular course is on the analysis of data to develop spreadsheet decision models in a business environment. Topics may include linear programming, network modeling, goal programming, nonlinear programming, regression, data mining, forecasting, simulation, queuing theory and decision analysis.

DSCI 446. BUSINESS FORECASTING. 4 Credits.

Pre-requisites: DSCI 346 or equivalent or permission of the instructor.
Integrates several forecasting models with applications to managerial techniques. Topics include regression, multiple regression, time series analysis, autocorrelation, econometric models, exponential smoothing, autoregressive models, adaptive filtering, Box Jenkins methods, and survey techniques. The computer is employed to develop meaningful forecasts for management.

DSCI 447. DESIGN OF EXPERIMENTS. 4 Credits.

Pre-requisites: DSCI 346 or equivalent or permission of the instructor.
An in-depth study of quantitative business analysis techniques in a variety of organizational environments. Emphasizes the use of the computer and a discussion of quality in the organizational setting.

DSCI 448. BUSINESS SIMULATION. 4 Credits.

Pre-requisites: DSCI 346 or equivalent or permission of the instructor.
An examination of probabilistic robabilistic models in decision science, with emphasis on discrete event simulation.

DSCI 449. MULTIVARIATE DATA ANALYSIS. 4 Credits.

Pre-requisites: DSCI 346 or equivalent.
Multivariate data analysis methods are used in fields such as business, engineering, education, data mining and many others. This course examines the concepts and principles of the various statistical methods used in the analysis of multiple simultaneous measurements on the subjects under investigation. Software is heavily used to support the studies in this course.

DSCI 450. DATA VISUALIZATION. 4 Credits.

Pre-requisites: DSCI 346 or equivalent.
Data visualization helps people understand the information within data by placing it in a visual context. As statistical results are often communicated poorly in the media, in scientific journals and in business, this course examines methods used in the presentation of these results to non-statistically oriented audiences. A variety of software packages are used to develop appropriate data visualizations. Non-technical writing and presentation skills are emphasized.

DSCI 495. PROFESSIONAL INTERNSHIP. 1-15 Credits.

DSCI 498. SEMINAR. 1-15 Credits.

DSCI 499. DIRECTED STUDY. 1-5 Credits.

Pre-requisites: permission of the instructor, department chair and college dean.
