Normal Distributions: Interactive Parameter Exploration

① This GeoGebra example dynamically demonstrates normal distribution curves, allowing users to adjust mean and standard deviation parameters to observe shape changes. ② Core mathematical concepts include the normal probability density function, the role of mean (location) and standard deviation (scale) in shifting and stretching the curve, and symmetry. ③ Construction uses the Normal command to generate distribution functions, Textfield input boxes and sliders (objects a, b, c, d) for parameter control, text objects (text1, text2) to display values, and function objects f and g for curves. ④ Suitable for high school and college statistics/probability courses, ideal for understanding parameter effects, comparing distributions, and as an interactive teaching tool.
