|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.
|Confidence Interval Creation:
An interactive applet is used to demonstrate creation and interpretation of confidence intervals. Users of the applet can manipulate the shape of the population distribution, sample size, and level of confidence.
|Introduction to Bootstrapping:
How does bootstrapping work? Why is it useful? This video uses an interactive applet to demonstrate the logic of bootstrapping, and construction of confidence intervals for non-normal distributions.
|Pearson’s Chi-Square Test:
This video introduces Pearson’s chi-square test, including background, logic, and applications.
