|The Normal Distribution:Why is the normal distribution so important when real distributions are rarely (never?) normal? This video explores characteristics of the normal distribution with a bit of history and some fun facts.|
An interactive applet is used to demonstrate the sampling distribution of the mean and how it is related to sample size and the population distribution.
|Confidence Interval Game:
This video demonstrates a common misinterpretation of confidence intervals and a game to help users improve their accuracy in interpreting confidence intervals.
