A poem to illustrate the dependence between trials when sampling is without replacement. To set this poem up in the classroom, you might ask the students questions like: "If I want to put the Supreme Court Justices in a random order, I can pick one at a time without replacement. Before I pick the first Justice, do I know who it's going to be? Before I pick the last Justice, do I know who it's going to be?" The poem was written in 2017 by Larry Lesser from The University of Texas at El Paso.

A cartoon to teach about the relationship between population and sample and correspondingly between parameter and statistic. Cartoon by John Landers (www.landers.co.uk) based on an idea from Dennis Pearl (The Ohio State University). Free to use in the classroom and on course web sites.

A cartoon to teach about the value of random sampling to control bias and provide the underpinning for inference. Cartoon by John Landers (www.landers.co.uk) based on an idea from Dennis Pearl (The Ohio State University). Free to use in the classroom and on course web sites.

The textbook for this course discusses cross-cultural variations in household structure, as well as changes across time in household structure in the United States. The purpose of this exercise is to examine variations in household structure in the United States according to race and historical period. By the end of the exercise students should have a better appreciation of the fact that household structure in the U.S. is very fluid and that changes over time in household structure have not progressed uniformly for all race groups.

The datasets in this collection are in text format, but are also compatible with Arc software from "Regression Graphics." Each set has a title, description, and data table. The software is available in the relation link below.

HotBits is a genuine random number generator powered by radioactive decay. Simply click the "Request HotBits" link, and specify how many bytes you would like (up to 2048) and in what form you prefer them. Hexadecimal returns numbers and letters, while C language returns integers. Then click the "Get HotBits" button, and your random numbers will appear on the screen.

This pdf document contains 7 pages of random number tables and 1 page of instructions for use.

This demonstration allows you to view the binomial distribution and the normal approximation to it as a function of the probability of a success on a given trial and the number of trials. It can be used to compute binomial probabilities and normal approximations of those probabilities.
