| APPLET | SOURCE | DESCRIPTION |
|
| Constructing simple confidence intervals | Lamb | Walks user through process of constructing a confidence interval using t, applet will calculate sample mean and standard deviation but user must use calculator and t distribution to do the remaining calculations. more |
| One sample CI for the mean with known population standard deviation | Dept of Statistics, Texas A&M University | Calculates confidence intervals for a mean using the normal distribution and summary statistics, nice feature allows a slider to increase or decrease the confidence level one percent at a time. more |
| One sample CI for the mean with unknown population standard deviation | Dept of Statistics, Texas A&M University | Calculates 95% or 99% confidence intervals for a mean using the t distribution and summary statistics. more |
| SOCR Analyses, ConfidenceInterval | SOCR (Statistics Online Computational Resource) | Computes confidence intervals for mean, proportion or variance given entered data. more |
| Online Descriptive Statistics | Xuru's Website | Calculates 50%, 90%, 95%, 99%, 99.5% and 99.9% confidence intervals for both mean and standard deviation for data that can be entered or pasted in. more |
| Confidence Interval of a Standard Deviation | GraphPad QuickCalcs | Calculates 90%, 95% and 99% confidence intervals for a standard deviation based on either observations entered one by one, a column of data pasted in, or summary information. more |
| One sample CI for the variance | Dept of Statistics, Texas A&M University | Calculates confidence intervals for the variance based on summary statistics, nice feature allows a slider to increase or decrease the confidence level one percent at a time. more |
| Percentage: Estimation & Testing/Exact Confidence Interval Construction and Test of Hypothesis for T | A Collection of JavaScript E-labs Learning Objects (Arsham) | Computes confidence interval for a proportion for finite or infinite populations based on sample size and number of successes. more |
