The Normal Distribution (Geogebra)

This is a Geogebra (v5.0) application designed to help students understand the concepts and properties of the Normal probability distribution.

You can change the lower and upper boundaries in both the x-score and z-score forms. You can show/hide the probability between the lower and upper boundaries or reveal the left and right tail probabilities.

You can also set the mean and standard deviation to generate questions for the students to practice. Changing the standard deviation will dynamically show students how the spread of the normal distribution changes.

You can also show the points of inflection on the curve and how this is located at ±1 standard deviation.

Students will appreciate the visual engagement of the program and you, as the teacher, will appreciate the time saved in being able to quickly and clearly present solutions.
