| APPLET | SOURCE | DESCRIPTION |
|
| Z-scores/ Area under the normal distribution | Reed | Shows graphically cumulative probabilities for entered z-scores and how these values are found from a standard normal table. more |
|
| NormalArea | Seeing Statistics with Bolder Stats | Shows visually how rectangles can be used to approximate area under the standard normal curve. more |
|
| Standard Normal Distribution | Southern Polytechnic State Univ. Math Dept. | Calculates and shows graphically area/probability on the standard normal between any two specified z-scores. more |
|
| NormalProb | Seeing Statistics with Bolder Stats | Calculates and shows graphically two-tailed probabilities from a z-score or vise-versa. more |
|
| Standard Normal Curve | SticiGui (Stark) | Calculates and shows graphically left, right and interior probabilities for a standard normal. more |
|
| Working with z-scores and normal probabilities | Seeing Statistics (McClelland) | Calculates z-score from summary sample data and shows graphically one-tailed, two-tailed, cumulative and interior probabilities for the standard normal. more |
|
| Probability and Quantile Applets | Narasimhan | Calculates and shows graphically either left, right or interior probabilities from z-scores for a standard normal, or the x values associated with a specified cumulative probability for any normal. more |
|
| Standardizing a normal random variable | U. Michigan-Dearborn, Economics | Walks user through steps of standardizing a normal, visualizing graphs, and finding associated probabilities using a normal table. more |
