Linear Regression & Correlation Interactive
Linear Regression & Correlation Interactive is a free, interactive learning demo from the Introductory Statistics course on Lykke. It helps you build intuition for Correlation Coefficient (r), Least-Squares Regression Line, Coefficient of Determination (r^2), Residuals. Play with it directly in your browser — it features 5 buttons and direct drag interaction. This demo lives in the “Linear Regression and Correlation” section of the course.
How to use this demo
- Click and drag directly on the canvas to manipulate the scene.
- Use the “Strong +”, “Weak”, “Strong -”, “Outlier” buttons to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Correlation Coefficient (r)
- Least-Squares Regression Line
- Coefficient of Determination (r^2)
- Residuals
Frequently asked questions
What does the Linear Regression & Correlation Interactive demo do?
Modeling the relationship between two quantitative variables and predicting outcomes. Linear Regression & Correlation Interactive turns that idea into something you can manipulate directly and watch respond.
What Introductory Statistics concept does Linear Regression & Correlation Interactive teach?
Modeling the relationship between two quantitative variables and predicting outcomes. It focuses on Correlation Coefficient (r), Least-Squares Regression Line, Coefficient of Determination (r^2), Residuals from the “Linear Regression and Correlation” section.
What can I control in Linear Regression & Correlation Interactive?
You can drag elements directly on the canvas; the “Strong +”, “Weak”, “Strong -”, “Outlier” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Linear Regression & Correlation Interactive fit into the Introductory Statistics course?
Introductory Statistics 2e is a comprehensive, open-source course designed for a one-semester introduction to statistics. The curriculum focuses on practical applications across diverse fields such as business, healthca… This demo is the interactive piece for the “Linear Regression and Correlation” section.

What will I understand better after using Linear Regression & Correlation Interactive?
You'll build intuition for Correlation Coefficient (r), Least-Squares Regression Line, Coefficient of Determination (r^2), Residuals — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Introductory Statistics alone.
