• Histogram Applet -- shows how the number and width of the bins can affect the appearance of a histogram (West and Ogden)

• Normal Distribution Applet -- draws a normal curve with a specified mean and standard deviation and demonstrates the 68-95-99.7 rule for normal distributions (Balasubramanian Narasimhan)

• Areas Under Normal Curves -- two applets that calculate areas under the standard normal curve and calculate percentiles for any normal distribution (Balasubramanian Narasimhan)

• Central Limit Theorem Applet -- demonstrates the Central Limit Theorem using simulated dice-rolling experiments (West and Ogden)

• Scatterplots and Correlation Applet -- shows the relationship between the appearance of a scatterplot and the value of the correlation coefficient (Juha Puranen)

• Guessing Correlations Applet -- a "game" that lets you guess the value of the correlation for a given scatterplot (from University of Illinois at Urbana-Champaign)

• Regression Applet -- shows the effect of leverage points on a regression line (West and Ogden)

• Confidence Interval Applet -- demonstrates how confidence intervals work by computing 50 confidence intervals for the mean in a situation where the true mean is known to be 0 (West and Ogden)

• Power of a Hypothesis Test Applet -- demonstrates the principles of hypothesis testing using a test for a mean (West and Ogden)

• Let's Make a Deal Applet -- demonstrates the Monty Hall three-door problem (West and Ogden)
