Courses may be offered in one of the following modalities:

• Traditional in-person courses (0–29 percent of coursework is delivered online, the majority being offered in person.)
• Hybrid/blended courses (30–79 percent of coursework is delivered online.)
• Online courses (100 percent of coursework is delivered online, either synchronously on a designated day and time or asynchronously as a deadline-driven course.)
• Hyflex (Students will be assigned to attend in-person or live streamed sessions as a reduced-size cohort on a rotating basis; live sessions are also recorded, offering students the option to participate synchronously or view asynchronously as needed.)

If you are enrolled in courses delivered in traditional or hybrid modalities, you will be expected to attend face-to-face instruction as scheduled.

DSC 670: Statistical Methods

3 credits

Organizations confront a myriad of problems characterized by uncertainty in the environment. The decision making process requires models, analysis, and solutions that account for this uncertainty, and statistics provides a methodology that assists in the resolution of those issues. Topics include probability, sampling distributions, parameter estimation, hypothesis testing, regression/correlation.

Learning Goals

After completing this course, you should be able to:1. Use measures of central tendency (mean, median, and mode) and dispersion (variance and standard deviation) to summarize numeric data2. Describe the distributions of many economic variables - both discrete and continuous3. Show how probability distributions are used to characterize the nature of random variables (such as revenues, earnings, interest rates, and customer demographic data)4. Describe the properties of a good estimator, and be able to identify the appropriate probability distribution for each estimator5. Calculate both point and interval estimates for each population parameter introduced in class6. Carry out a test of hypothesis for a single population.7. Explain the concept of regression, and then show how a regression model could be used to determine relationships between variables in simple linear forms8. Explain the difference between a simple linear model and a multiple regression model
