# Java Applet

• ### Song: Empty Time with Normal Tables

A song that might be used in pre-service courses for statistics teachers (or professional development workshops) to point out why using technology is preferred to training students to use Normal Probability Tables. The lyrics were composed by Robert Carver of Stonehill College. May be sung to the tune of the "Empty Chairs at Empty Tables" written by Schoenberg and Kretmer for the play Les Miserables. The lyrics won an honorable mention in the CAUSE 2013 A-Mu-sing contest. Musical accompaniment realization and vocals are by Joshua Lintz from University of Texas at El Paso.
• ### Cartoon: Breaking News

A cartoon for teaching about using the t-distribution for inference when the standard deviation is unknown. The cartoon was created by Karen Banks from University of Indiana using the software at www.bitstrips.com. The cartoon also won a prize in the CAUSE 2013 A-Mu-sing contest.
• ### Statistics JAVA Applets

This is an extensive collection (and a continuously expanding collection) of applets on topics that include probability, descriptive statistics, sampling distributions, Monte Carlo simulation, Buffon's coin problem, chi-square, p-values, correlation, and more. There is even a random number generator that is part of the collection.

• ### **Probability Histograms

This simulation allows you to roll two dice and compare empirical and probability histograms for the sum or product of the two outcomes.

• ### Webinar: Helping Students Understand the Meaning of Random: Addressing Lexical Ambiguity

August 10, 2010 T&L webinar presented by Diane Fisher (University of Louisiana at Lafayette), Jennifer Kaplan (Michigan State University), and Neal Rogness (Grand Valley State University) and hosted by Jackie Miller(The Ohio State University). Our research shows that half of the students entering a statistics course use the word random colloquially to mean, "haphazard" or "out of the ordinary." Another large subset of students define random as, "selecting without prior knowledge or criteria." At the end of the semester, only 8% of students we studied gave a correct statistical definition for the word random and most students still define random as, "selecting without order or reason." In this session we will present a classroom approach to help students better understand what statisticians mean by random or randomness as well as preliminary results of the affect of this approach.
• ### Webinar: Using Baboon "Mothering" Behavior to Teach Permutation Tests

September 14, 2010 T&L webinar presented by Thomas Moore(Grinnell College) and hosted by Jackie Miller(The Ohio State University). Permutation tests and randomization tests were introduced almost a century ago, well before inexpensive, high-speed computing made them feasible to use. Fisher and Pitman showed the two-sample t-test could approximate the permutation test in a two independent groups experiment. Today many statistics educators are returning to the permutation test as a more intuitive way to teach hypothesis testing. In this presentation, I will show an interesting teaching example about primate behavior that illustrates how simple permutation tests are to use, even with a messier data set that admits of no obvious and easy-to-compute approximation.
• ### Stat.Istics site

This site is a collection of interesting stories in the news that relate to statistics, major league baseball standings, links to textbooks, and links to applets. It also contains some reflections on statistical issues from retired professor John Marden (from University of Illiois at Urbana-Champaign).

• ### Cartoon: The Relationship Graph

A cartoon to help in teaching the importance of labeling the axes of a graph. The cartoon is number 833 (December 2010)  from the webcomic series at xkcd.com created by Randall Munroe.

• ### Quote: Varian on Statisticians

I keep saying that the sexy job in the next 10 years will be statisticians is a quote from American economist Hal R. Varian (1947 -) quoted in an August 5, 2009 "New York Times" article "For Today's Graduate, Just One Word: Statistics," written by reporter Steve Lohr. The article may be found online at www.nytimes.com/2009/08/06/technology/06stats.html
• ### Quote: Tufte on Graphics

At their best, graphics are instruments for reasoning about quantitative information. is a quote by American statistician and political scientist Edward R. Tufte (1942 - ). The quote appears on page 9 of Tufte's 1983 book "The Visual Display of Quantitative Information".
