This example demonstrates linear regression analysis using GeoGebra, showing how to fit a best-fit line to data points and calculate the correlation coefficient (PMCC). Core math concepts include linear regression, correlation coefficient, data distribution, and frequency distribution. It uses commands like Corner, Polygon, PointIn, FitPoly, PMCC, and LaTeX with objects such as points R, Q, L, M, K, N, etc. Suitable for high school mathematics teaching, focusing on data analysis and statistical modeling.
