| APPLET | SOURCE | DESCRIPTION |
|
| Normal Quantiles | Statistical Java (Dorai-Raj, Anderson-Cook, Robinson) | Calculates and shows graphically the x value associated with the specified left- or right tail probabilities on any normal. more |
| Empirical Rule Demonstration | Applets for the Cybergnostics project (West) | For any normal, calculates and shows graphically probability of being within a specified number of standard deviations. more |
| Convert to Standard Scores | Vassar Stats (Lowry) | For data entered or pasted into a column, calculates z-score of each observation based on either sample or population standard deviation. more |
| Normal Distributions | Vassar Stats (Lowry) | For any normal, tabulates one and two tail probabilities for specific values. more |
| Probability Distribution Applet | FortuneCity | Use like statistical table (with graphical display) for many continuous and discrete distributions, calculates cumulative or tail probabilities from given values. more |
| Decision Visualizer | BrightStat.com | Use like statistical table (with graphical display) for a standard normal, Student's t, chi-square or F distribution, display visually the upper, lower, one or two-tailed probabilities for a given value or the values for a specified probability. Requires free download of executable file. more |
| Probability Distribution Functions | Statpages.org, (Pezzullo) | Use like statistical table for a standard normal, Student's t, chi-square or F distribution: calculates right tail probabilities from values or vise versa. more |
