FunctionProbability & StatisticsGraphing
This example demonstrates the characteristics of the normal distribution. It involves core concepts of probability and statistics, using GeoGebra commands such as Segment, Point, Histogram, Mean, SD, BoxPlot, Normal, Polygon, and NormalQuantilePlot to construct an intuitive normal distribution graph. Suitable for high school and above students or teachers to understand the shape, mean, standard deviation, and other aspects of the normal distribution.
