ECON 2331
Economic and Business Statistics 2

3.0 Credits


Building on STAT 1201: Introduction to Probability and Statistics, students examine advanced statistical techniques and methods and their applications in business and economics. Topics include review of hypothesis tests; inferences about population variances; comparing multiple proportions for three or more populations and tests of independence; analysis of variance and experimental design; simple and multiple regressions; and time series analysis and forecasting. Students are required to apply statistical techniques using Excel® and/or XLSTAT®.

Delivery Method

Online, self-paced.


Recommended: ECON 1221 or ECON 1901 and ECON 1951; STAT 1201, MIST 2611


After completing this course, students should be able to:

  • Demonstrate how to test hypotheses, including nonparametric methods.
  • Test for the equality of three or more population proportions.
  • Conduct analysis of variance under various experimental designs
  • Estimate simple and multiple regression models and interpret the results.
  • Use time series analysis and forecasting models to make accurate forecasts.
  • Apply statistical techniques to various fields such as marketing, supply chain management, finance, accounting, and economics using real-world data.
  • Demonstrate the ability to use Excel® and XLSTAT® in estimating applied statistical procedures, methods, and models.
