View Resource **Introduction to Probability Models

This applet simulates rolling dice and displays the outcomes in a histogram. Students can choose to roll 1, 2, 6, or 9 dice either 1, 10, 20, or 100 times. The outcome studied is the sum of the dice and a red line is drawn on the histogram to show expected number of occurences of each outcome.
View Resource **Java Applets for Power and Sample Size

This collection of free, interactive Java applets provides a graphical interface for studying the power of the most commonly encountered experimental designs. Intended to be useful in planning statistical studies, these applets cover confidence intervals for means or proportions, one and two sample hypothesis tests for means or proportions, linear regression, balanced ANOVA designs, and tests of...
View Resource **Java Demos for Probability and Statistics

The applet demonstrates, in a visual manner, the following probability and statistical concepts (and there is also a random number generator): Introduction to Probability Models (Using dice rolls), Hypergeometric Distribution, Poisson Distribution, Normal Distribution, Hypothesis Testing for Proportions, Confidence Intervals for Means, The Central Limit Theorem, Bivariate Normal Distribution, and...
View Resource **Least Squares Demo

This simulation illustrates least squares regression and how the least squares solution minimizes the sum of the squared residuals. The applet demonstrates, in a visual manner, various concepts related to least squares regression. These include residuals, sum of squares, the mean line, how the line of best fit is determined, and how the line of least squares solution minimizes the sum of the...
View Resource **Lesson Plan: Univariate Statistics

This is a lesson plan for 16 to 17 year old students that focuses on developing students' understanding of the relative strengths and weaknesses of various representations of real world univariate statistics. Students work in groups to research different visual representations and create a wiki page of their findings.
