In this section we present materials that can be used for lecture topics and to supplement the presentation of materials to students. Materials here include detailed explanations of topics, PowerPoint presentations, and detailed examples that can be used in a lecture setting.
** Histograms on Anova
This simulation applet is designed to demonstrate the sampling distributions of the F statistic, Mean Square Error (MSE), and Mean Square Treatment (MSTR) for one-way Analysis of Variance (ANOVA).
** Regression
This applet from Statistical Java allows the user to generate bivariate data for analysis with simple linear regression. The page describes the equations used to generate the data and estimate the...
**Dotplot Summaries Applet
This applet generates dotplots for different data sets and allows users to guess the location of various measures of center and spread. Clicking "Resample” produces a dotplot of random data generated...
**Histograms on Linear Regression
This applet simulates a linear regression plot and the corresponding intercept and slope histograms. The program allows the user to change settings such as slope, standard deviation, sample size, and...
**Interactive Games
This applet allows users to play several probability games like Monty Hall, Gambler's Ruin, Galton's Board, etc. Select a game from the drop down menu and click "About" to read its background.
**Introduction to Control Charts
This site provides resources for basic variable and attribute data set analysis and formulas to plot control charts. It provides basic mathematical formulas to plot control charts. It shows examples...
**Reese's Pieces Samples
This applet simulates drawing samples of Reese’s Pieces from a candy machine. Users set the sample size, number of samples, and theta, the population proportion of orange pieces. The applet keeps...
**Simulating Binomial Distribution Applet
This applet simulates drawing samples from a binomial distribution. Users set the population proportion of success (pi), sample size (n), and number of samples. By clicking “Draw Samples,” the applet...
**Simulating Confidence Intervals
This applet generates confidence intervals for means or proportions. The options for confidence intervals for means include “z with sigma,” “z with s,” or “t.” The options for confidence intervals...
**Type I and Type II Errors - Making Mistakes in the Justice System
This webpage uses the criminal trials in the US Justice system to illustrate hypothesis testing, type I error, and type II error. An applet allows the user to examine the probability of type I errors...
