Correlation and Regression Line Game
Loading the math board and drawing, please wait…
Adjust the positions of points to observe the changes in the correlation coefficient and the least squares regression line. This example demonstrates how the movement of points affects correlation and the regression line. Key mathematical concepts include correlation and least squares method. GeoGebra commands used include PMCC and polynomial fitting. Suitable for high school math education to help students understand the relationship between data.
