Confidence Intervals for the Weibull distribution
Comparing the lengths of nonsymetric CI’s with that of the symmetric CI of the same level of confidence. Select the level of confidence $(1a)*100$ by chosing the value of $a$. Select the value of the shape parameter $k$ of the Weibull distribution. The symmetric CI has equal probability of the left and right tails.

Confidence Intervals of Minimal Length for the F Distribution
We minimise the lengths of confidence intervals of a given level of confidence by varying the tail probabilities ratio. Select the level of confidence $(1a)*100$ by chosing the value of $a$. Select the two values of the degrees of freedom, $n$ for the numerator and $m$ for the denominator of the Fdistribution. The symmetric CI […] 
Bivariate normal and regression lines
Visualise how the regression lines E(YX) and E(XY) change when the values of the parameters of the given bivariate normal change.melbapplets.ms.unimelb.edu.au/2024/10/09/bivariatenormalandregressionlines

Confidence intervals, hypothesis testing and pvalues
This applet illustrates the connection between a confidence interval, a formal hypothesis test, and the pvalue of a hypothesis test.melbapplets.ms.unimelb.edu.au/2021/07/12/confidenceintervalshypothesistestingandpvalues

Power of a hypothesis test
This applet gives a visualisation of the concept of statistical power, and helps illustrate the relationship between power, sample size, standard deviation and difference between the means.melbapplets.ms.unimelb.edu.au/2021/07/12/powerofahypothesistest

Partitioning of variability in regression
This applet illustrates partitioning of variability into explained (fitted) and unexplained (residual) variability.melbapplets.ms.unimelb.edu.au/2021/07/12/partitioningofvariabilityinregression

Partitioning of variability in ANOVA
This applet illustrates the partitioning of variability into explained and unexplained variability, in the context of ANOVA.melbapplets.ms.unimelb.edu.au/2021/07/12/partitioningofvariabilityinanova

Distribution of order statistics
This applet displays the distribution for the order statististics of a sample of size n from an arbitrary population distribution.melbapplets.ms.unimelb.edu.au/2021/07/12/distributionoforderstatistics
