4434Visual Analysis of Variance (ANOVA)
http://www.merlot.org/merlot/viewMaterial.htm?id=89485
Visual ANOVA is an interactive Flash program which demonstrates visually how variability between and within experimental groups contributes to the F ratio in the Analysis of Variance. It is not a numerical calculator; rather it visually and holistically demonstrates the relations among important concepts. Visual ANOVA is supported by online instructions and by an extensive online lecture explaining the theory behind the Analysis of Variance. The online lecture is supported by two types of assignments: 1) Online computer-graded homework, and 2) A pdf file that gives students the opportunity to do handwritten homework problems with answer keys.Introductory Statistics / Collaborative Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=334307
Introductory Statistics is the next generation of Collaborative Statistics and was written by Barbara Illowsky and Susan Dean, faculty members at De Anza College in Cupertino, California. The textbook was developed over several years and has been used in regular and honors-level classroom settings and in distance learning classes. This textbook is intended for introductory statistics courses being taken by students at two and four year colleges who are majoring in fields other than math or engineering. Intermediate algebra is the only prerequisite. The book focuses on applications of statistical knowledge rather than the theory behind it.Difference to Inference: Using Deductive and Inductive Logic to make Inferences
http://www.merlot.org/merlot/viewMaterial.htm?id=89228
Difference to Inference is an online JAVA program simulating theory testing and falsification through research design and data collection in a game format. The program, based on cognitive and epistemological principles, is designed to support the learning of thinking skills underlying deductive and inductive logic and statistical reasoning. Students must strategically plan a series of studies and then use the data from those studies to eliminate competing theories. Difference to Inference has database connectivity so that game scores can be counted as part of course grades. No other assignments are necessary. Difference to Inference is supported by an online tutorial for its use and by an online course lecture explaining the principles of scientific methodology behind its play. A companion game whose play fits extremely well with Difference to Inference (for teaching scientific methodology) is called "Detect Difference." Articles about Difference to Inference can be found in the May 2001 issue of Behavior Research Methods Instruments & Computers and in The Journal of Infomation Technology in Medicine (2000).Gapminder
http://www.merlot.org/merlot/viewMaterial.htm?id=532981
Gapminder is the creation of Swedish academic Hans Rosling. The site contains a growing collection of resources useful to teachers interested in demographic data and vital statistics for the countries of the world.One of the most remarkable features on the site is Gapminder World, a very powerful, web-based data visualization tool that allows instructors and students to quickly visualize and further investigate vital statistics for the world's nations and the development of those statistics over time. The Wealth and Health of Nations tracks the development of life expectancy versus wealth for the countries of the world from 1800 in an engagingly visualized animation. There are numerous of the data sets that can be used in place of the default life expectancy versus GDP/capita.In addition to this remarkable resource, there are videos and specific resources for teachers on the site. Gapminder is a site is not easily summarized. But one that may be of interest to instructors interested in global issues from disciplines as diverse as statistics to history.TeachingWithData
http://www.merlot.org/merlot/viewMaterial.htm?id=700818
A repository of tools and educational materials designed to improve quantitative literacy skills in social science courses. Built especially for faculty teaching post-secondary courses in such areas as demography, economics, geography, political science, social psychology, and sociology, the materials include stand-alone learning activities, tools, and pedagogy services. The goal is to make it easier for faculty to bring real social science data into courses across the curriculum ranging from introductory classes to senior seminars.Statistical Home Page
http://www.merlot.org/merlot/viewMaterial.htm?id=87797
This statistical homepage contains educational material of interest to faculty and students studying statistics. It is intended to augment the author's textbooks entitled "Statistical Methods for Psychology" and "Fundamental Statistics for the Behavioral Sciences."Normal Probability Tool
http://www.merlot.org/merlot/viewMaterial.htm?id=91030
A simple to use JAVA applet that finds Normal probabilities. Simply set mu, sigma, upper and lower scores. Normal Tool shows the area under the curve along with the probability. Detailed instructions are included. Optional web lecture on the Normal Probability Distribution is also included. Two kinds of Assignments are provided under the assignment link--one assignment is computer graded and uses a JAVA applet, the other assignment is a typical story problem homework with answer key in pdf format.Measures of Central Tendency & Outliers
http://www.merlot.org/merlot/viewMaterial.htm?id=469504
Share with your students why the presence of an outlier affects which measure of central tendency to report. Feel free to modify the presentation to fit the needs of your students. Included at the end are additional online resources to further engage your students in their learning about the mean, median, and mode.

http://www.merlot.org/merlot/viewMaterial.htm?id=82082
Multiple-Choice (MC) items have many advantages that make them widely used and highly regarded. They also have disadvantages, some of which can be reduced by careful attention to good item-writing and item analysis practice. This resource describes advantages and disadvantages of Multiple-Choice Items, General Guidelines, Item Stem Guidelines, and Item Options Guidelines. Links from this page also provide information about item analysis (overall test reliability and about individual items) and descriptive statistics.
