This applet illustrates the connection between a confidence interval, a formal hypothesis test, and the p-value 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.
This applet illustrates partitioning of variability into explained (fitted) and unexplained (residual) variability.
This applet illustrates the partitioning of variability into explained and unexplained variability, in the context of ANOVA.
This applet displays the distribution for the order statististics of a sample of size n from an arbitrary population distribution.
This applet shows the maximum likelihood estimator and (log) likelihood function for several statistical models.
This applet explores QQ-plots for a range of distributions.
This applet illustrates how the distribution of the sample mean converges towards normality as sample size increases.
