| Simulations and Demonstrations: Robustness | Rice Virtual Lab in Statistics (Lane) | Users adjust standard deviation and skew of two distributions and specify sample sizes, simulates Type I error rate to observe effects of violation of homoscedasticity and normality assumptions. more |
| One Way ANOVA | A Calculating Companion for Brunett's Critical Thinking | For up to 9 groups of user entered data, creates ANOVA table, calculates p-values, draws conclusions and gives q values for post hoc comparisons of all pairs and critical values of the studentized range statistic. more |
| Post Test Calculator | GraphPad QuickCalcs | Computes t statistics and p-values for comparisons and confidence intervals for differences for up to 50 comparisons based on user-entered mean square error, degrees of freedom, and group means and sample sizes. more |
| Least significant difference (Tukey) | Dept. of Obstetrics and Gynaecology, Chinese Univ. of Hong Kong | Computes least significant difference (Tukey) from degrees of freedom and mean square error. more |
| Least significant difference (Scheffe) | Dept. of Obstetrics and Gynaecology, Chinese Univ. of Hong Kong | Computes least significant difference (Scheffe) from degrees of freedom, mean square error and sample sizes. more |
| Tukey Post Hoc Calculator | Psychology World, Virtual Statistician (Hall) | Walks through steps of calculating Tukey's HSD based on user entered means, MSW, and sample size, user must then compare to table of critical Q values. more |
| Tukey's Post Hoc Test | Psychology World, Virtual Statistician (Hall) | Calculating Tukey's HSD for four groups based on user entered means, MSW, and sample size, user must then compare to table of critical Q values. more |
| Homogeneity of Multi-variances: The Bartlett's Test | A Collection of JavaScript E-labs Learning Objects (Arsham) | Computes p-value for Bartlett's test for homogeneity of variance for up to 14 groups based on user-entered sample sizes and variances. more |
