Standardizing the Normal Distribution
- Georgia Stuart
Drag the mean, standard deviation, and x value around. Observe the changes in the area of the shaded portions under the normal distribution and standard normal distribution curves, and the value of z.
Questions to consider: 1. How does changing x affect z? 2. How does changing the mean or standard deviation affect z? 3. How does changing the mean or standard deviation affect area? 4. What's the connection between the area on the standard normal distribution and the normal distribution?
