 The Normal Distribution and Density The user is be able to change the mean and the standard deviation using the sliders and see the density change graphically. The check buttons (68, 95, 99) will help one realize the appropriate percentages of the area under the curve. An example of this "68-95-99.7" rule follows. Overall this site, created by author Balasubramanian Narasimhan of Stanford University, is a good resource to help... http://statweb.stanford.edu/~naras/jsm/NormalDensity/NormalD...
 Bernoulli Trials This online, interactive lesson on Bernoulli provides examples, exercises, and applets. The site, created by Kyle Siegrist of the University of Alabama - Huntsville, covers binomial, geometric, negative binomial, and multinomial distributions. This page is a part of a much larger virtual laboratory on mathematics. It provides a great overview of Bernoulli trials, but also links users to... http://www.math.uah.edu/stat/bernoulli/
 Monte Carlo Estimation for Pi This is the description and instructions for the Monte Carlo Estimation of Pi applet. It is a simulation of throwing darts at a figure of a circle inscribed in a square. It shows the relationship between the geometry of the figure and the statistical outcome of throwing the darts. http://polymer.bu.edu/java/java/montepi/MontePi.html
 Sampling: Statnotes from NCSU's Public Administration Program Sampling is choosing which subjects to measure in a research project. Usually the subjects are people, but subjects could also be organizations, cities, even nations. Measurement is typically accomplished through survey instruments, but could also be by observation, archival record, or other method. Regardless, sampling will determine how much and how well the researcher may generalize his or her... http://faculty.chass.ncsu.edu/garson/PA765/sampling.htm
 Confidence Intervals The applets in this section of Statistical Java allow you to see how levels of confidence are achieved through repeated sampling. The confidence intervals are related to the probability of successes in a Binomial experiment. The main page gives the equation for finding confidence intervals and describes the parameters (p, n, alpha). Each applet allows you to change a different parameter and... https://www.causeweb.org/repository/statjava/CI.html
