FunctionCoordinate GeometryProbability & Statistics
This example demonstrates how to dynamically visualize and calculate the correlation coefficient using Z points. It involves core math concepts like correlation coefficient, linear functions, conditional probability, and geometric shapes (pie chart, trapezoid). Key GeoGebra commands used include SDX, SDY, MeanX, MeanY, PMCC, Element, FitLineY, with objects A to M and list1. Suitable for high school and above mathematics education, combining probability statistics with analytical geometry.
