Confidence intervals, hypothesis testing and p-valuesThis applet illustrates the connection between a confidence interval, a formal hypothesis test, and the p-value of a hypothesis test.
Power of a hypothesis testThis 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.
Partitioning of variability in regressionThis applet illustrates partitioning of variability into explained (fitted) and unexplained (residual) variability.
Partitioning of variability in ANOVAThis applet illustrates the partitioning of variability into explained and unexplained variability, in the context of ANOVA.
Normal approximation to the binomial distributionThis applet explores the normal approximation to the binomial distribution.
Discrete and continuous distributionsThis applet explores the relationship between the pmf or density and the cumulative distribution function of a range of discrete and continuous probability distributions.
Normal probability plot and CDFThis applet shows the relationship between a plot of an estimated empirical CDF and a normal probability plot.
QQ plotsThis applet explores QQ-plots for a range of distributions.
Random variablesThis applet illustrates the concept of independent identically distributed random variables.
