Scheaffer, R. L., & Lee, C. (2000). The case for undergraduate statistics. This is a good article discussing the importance of learning statistics.
Statistical Assessment Service
This is a non-partisan, non-profit research organization in Washington, D.C. Its focus is the accurate use of scientific and social research in public policy. There are many good articles and examples of error or misuse of statistics in the press.
Chapter 2: Frequency Distribution Resources for Students and the Media Polling Report.com
A collection of recent poll results on business, politics and society from many different sources. Shows table summaries and changes over time
The National Sleep Foundation
Statistics with frequency distributions of a 2000 study just released.
Chapter 3: Graphs Histogram Applet by R. West, University of South Carolina
This is an interactive applet that demonstrates how bin width affects a histogram. The durations of eruptions of the Old Faithful geyser is the dataset used.
Histogram Simulation and Applet by Rice Virtual Lab
The exercise is a nice demonstrating bin width changes. Students can choose a dataset and explore the changes.
The Gallery of Data Visualization and the Best and Worst Statistical Graphics
This website has examples of some of the best and worst published graphs.
Chapter 4: Measures of Central Tendency The Data Applet
Students can interact with this applet by selecting the dataset and computing measures of central tendency or boxplots and comparing with the applet answer.
Teaching Applets by Vestac
Many applets that demonstrate central tendency. Interactive and nicely done Boxplots are also drawn.
The Mean and Median Simulations and Demonstration by Rice Virtual Lab
The demonstration begins with an applet and demonstrates mean and media. By changing the histogram, the central tendency can be modified.
Chapter 5: Measures of Variability Baseball Salary Activity with Data and Activity Sheet by Ed Malczewski
This activity explores the concept of variance.
A Quick Time Movie – Demonstrating the Mean by Berrie Teaching Applets by Vestac
Many applets that demonstrate variability. Interactive and nicely done.
Chapter 6: Scales Scores and Standard Scores: How to Change Apples into Oranges Scaled Scores and Anxiety by Paul Kenyon, University of Plymouth
Show the relationship between scaled anxiety scores and population percentile ranks. Applied use of course material is demonstrated nicely here.
Chapter 7: The Normal Curve A Quick Time Movie Demonstrating Normal Distribution by Berrie The Normal Distribution Applet by Narasimhan
Demonstrates the changes to the distribution as n increases and/or the standard deviation increases.
Chapter 8: Correlation Applet Demonstrating Restricted Range on Correlation by Rice Virtual Lab
Demonstration of the effect of restricted range. Students pick data sets and the scatterplot, r, regression equation, and standard error of the estimate are displayed.
Guessing Correlations by John Mardin
Match up scatterplots with correlation coefficients. Instructors that would like to set up a group so that their students can compete among themselves can send a request to stat100.
The life and work of Karl Pearson
The Karl Pearson Reader's Guide by John Aldrich, University of Southampton, Southampton, UK.
Interact With a Scatterplot – See Different Correlation Coefficients
This is a great way to see what different correlation coefficients look like on a scatterplot. You select the coefficient and the applet changes the scatterplot to match your selection.
Chapter 9: Regression Graphing Tools – 2D and 3D Scatterplots by J. Behrens, Arizona State University
This is a great demonstration for understanding regression. There are clear instructions to use the applets, explanation of concept, and an activity.
Regression Applet by R. West, University of South Carolina
An interactive applet that gives students an opportunity to see and subsequently understand the effect of outliers on regression analysis.
Chapter 10: Probability Theory and Sampling Tutorial on the Central Limit Theorem by WISE
Illustrates the basic principles of the Central Limit Theorem and enhances conceptual understanding of inferential statistics.
Sampling Distributions of the Mean by WISE
This tutorial teaches fundamental properties of sampling distributions of means such as accuracy of sample means, probability, and effects of sample size.
Probability by Surprise (Games Using Applets)
The Birthday Problem, Say Red, The Collector, The Matching Problem, Random Scatter, Traffic jams, Visualizing Probabilities, and more. The site has class notes for teaching probability that are used in an Introduction to Probability class taught at Stanford. The Stanford notes refer to these games and other web resources.
Miscellaneous
The International Shark Attack File located on the website of the Florida Museum of History has statistics that could be useful for probability and other topics.
Chapter 11: Experimental Design Choosing the Correct Statistical Test by WISE (Web Interface for Statistic Education)
This exercise poses different research scenarios and asks you what statistical test you would use to answer the research question of interest. An interesting approach to working with "real data". This is especially useful before the final exam.
