Data Science: Linear Regression is an introductory online course offered by the Harvard T.H. Chan School of Public Health and delivered through edX. The course teaches learners how to implement linear regression models using R, understand confounding, and analyze relationships between variables. Through practical case studies, including sports analytics inspired by Moneyball, participants gain hands-on experience applying statistical modeling techniques to real-world datasets.

What You’ll Learn in This Course?

This course enables learners to:

• Understand the historical development of linear regression and its statistical foundations

• Detect and interpret confounding variables in data relationships

• Implement linear regression models in R to analyze variable relationships

• Apply regression techniques to practical scenarios and predictive analytics

• Evaluate when regression is appropriate and understand its limitations

Accessibility and Value

The 100% online, self-paced course runs for 8 weeks with an estimated time commitment of 1- 2 hours per week. The course is available free of charge (with optional paid certification) and is designed for beginners exploring data science fundamentals.
