QST BA 221: Introduction to Data and Business Analytics
Undergraduate pre-requisite: QSTSM 131; students beyond first-year must take QSTSM 131 previously or concurrently. - Exposes students to business data and business analytics. Topics in business analytics include the fundamentals of probability and statistics, but the emphasis is on the collection, structuring, and analysis of data to support business decision-making. Topics include descriptive, predictive, and prescriptive analytics, as well as distributions, sampling, estimation, hypothesis testing, and chi-square analyses. Effective Fall 2025, this course fulfills a single unit in the following BU Hub area: Quantitative Reasoning I. -
QST BA 222: Modeling Business Decisions and Market Outcomes with Spreadsheets and Statistical Programming
Undergraduate Prerequisites: QSTBA 221. - Students must choose either QSTBA 222 or QSTBA 223, and students cannot take both courses. This course examines the use of economic and statistical tools for making business decisions at an advanced level, and prepares students for future study in business analytics. Introduces programming for data analysis (no previous programming knowledge required) and links data analysis to decision making using both spreadsheet modeling and statistical programming. Topics include multiple regression, causal inference, forecasting, predictive analytics, machine learning, demand modeling, and optimization. Case studies apply advanced concepts to practical business problems. Effective Spring 2021, this course fulfills a single unit in the following BU Hub area: Quantitative Reasoning II. -
QST BA 223: Business Modeling with Spreadsheets
Undergraduate pre-requisite: QSTBA 221. Formerly QSTQM 222. Students must choose either QSTBA 222 or QSTBA 223 (formerly QM222). Students cannot take both BA222 and BA223. - This course examines the use of economic and statistical tools for making business decisions. The course emphasizes linking data analysis to spreadsheet modeling to support advanced business decision making. Topics include multiple regression, causal inference, forecasting, demand modeling, and optimization. Case studies apply concepts to practical business problems and the principal software tool used in the course is the spreadsheet. Effective Fall 2025, this course fulfills a single unit in the following BU Hub area: Quantitative Reasoning 2. -
QST QM 323: Analytics
Pre-requisites: Questrom students only; QST AC221; BA221; BA222 or BA223; MO221; SM131; SM132; SM275 - Component of QST SM 323, The Cross Functional Core. Teaches quantitative methods and modeling techniques that will improve the student's ability to make informed decisions in an uncertain world. The two major modules of the course are models for optimal decision-making and decision- making under uncertainty. The first module focuses on methods and predictive models for decision-making; how optimization models are used to identify the best choice; and how choices change in response to changes in the model's parameters (sensitivity analysis). The second module covers the measurement and management of risk and Monte Carlo simulation. Throughout the semester, we will perform hands-on analysis that will improve Excel modeling skills; discuss the ethical use of data analytics; and learn to recognize pitfalls and biases in quantitative decision-making. cr.

QST QM 498: Directed Study: Quantitative Methods
Directed study in Quantitative Methods. 2 or 4 cr. Application available on Undergraduate Program website. -
QST QM 716: Business Analytics: Data Analysis and Risk
The overall goal of this course is to improve student ability to learn from data, specifically to 1) assess the validity of conclusions that have been drawn from statistical analyses; 2) recognize the extent to which variation characterizes products and processes, and understand the implications of variation on organizational decisions when interpreting data; and 3) portray, summarize and analyze data to support operational and strategic decisions associated with the core business models. Students will increase their understanding of the use of probabilities to reflect uncertainty; how to interpret data in light of uncertainty to assess risk; and how to build and interpret regression models, which can be used to inform core business and organizational decisions. -
QST QM 717: Data Analysis for Managerial Decision-Making
Graduate Prerequisites: (QSTMO712 OR QSTMO713) - The overall goal of this course is to improve student ability to learn from data, specifically to 1) assess the validity of conclusions that have been drawn from statistical analyses; 2) recognize the extent to which variation characterizes products and processes, and understand the implications of variation on organizational decisions when interpreting data; and 3) portray, summarize and analyze data to support operational and strategic decisions associated with the core business models.
