The Normal Distribution Curve by Robin Tunley

This interactive GeoGebra worksheet demonstrates the Gaussian (normal) distribution curve, allowing students to dynamically adjust the mean, amplitude, and standard deviation to observe how these parameters reshape the bell curve. Core mathematical concepts include the probability density function, the role of mean as location parameter, standard deviation as scale parameter, the area under the curve computed via definite integrals, and connections to binomial distribution and trigonometric functions. The construction uses commands such as Point, Segment, and Integral, with objects including the mean point m, standard deviation s, amplitude a, interval endpoints B and C, and multiple text labels for probabilities. Sliders enable real-time parameter changes)Skip. This resource is ideal for high school and undergraduate statistics or probability courses, helping students grasp the 68-95-99.7 rule, probability intervals, and the geometric interpretation of integration.
