As stated on the homepage for this site, "This site presents workbook-style, project-based material that emphasizes real world applications and conceptual understanding. This material is designed to give students a sense of the importance and allure of statistics early in their college career. By incorporating many of the successful reforms of the introductory statistics course into a wide range of more advanced topics we hope that students in any discipline can realize the intellectual content and broad applicability of statistics.״ http://www.merlot.org/merlot/viewMaterial.htm?id=564968 On this site, students can practice classifying statistics problems. They first click to check the statistical methods that they want to practice classifying. Then they click the "Submit" button to get a description of a research project that involves a statistical technique. Students then click on the technique that will most likely be used in the project. If they choose the incorrect answer, they must read the hint and try again. When they get something correct, they click on the "Next" button to try another problem. http://www.merlot.org/merlot/viewMaterial.htm?id=611033 This applet demonstrates the theory behind linear regression. http://www.merlot.org/merlot/viewMaterial.htm?id=611002 This is an applet that demonstrates least squares regression. http://www.merlot.org/merlot/viewMaterial.htm?id=582636 This site contains lots of helpful hints about how to easily type different mathematical expressions in e-mail messages (or in online discussion forums). This might be particularly helpful for online instructors who want students to talk about problems and share their work with others within the online environment. http://www.merlot.org/merlot/viewMaterial.htm?id=586732 Using a parameter it's possible to represent a property of an entire population with a single number instead of millions of individual data points. There are a number of possible parameters to choose from such as the median, mode, or interquartile range. Each is calculated in a different manner and illuminates the data from a different point of view. The mean is one of the most useful and widely used and helps us understand populations. A population is simulated by generating 10,000 floating point random numbers between 0 and 10. Sample means are displayed in histograms and analyzed. http://www.merlot.org/merlot/viewMaterial.htm?id=582623 The purpose of this resource is to illustrate some statistical concepts using QuickTime movies and Java applets. http://www.merlot.org/merlot/viewMaterial.htm?id=426107 This tutorial teaches students about statistical power and how it is influenced by a variety of features of the hypothesis testing situation. Students will be able to manipulate features of the test situation and see the effects on statistical power. http://www.merlot.org/merlot/viewMaterial.htm?id=710136 The WISE Bootstrapping Applet can be used to demonstrate bootstrapping by creating a confidence interval for a population mean or median. The user can manipulate the population distribution, sample size, and number of resamples. An associated guide gives suggestions for teaching bootstrapping. http://www.merlot.org/merlot/viewMaterial.htm?id=671721 This activity allows users to create and manipulate boxplots for either built-in data or their own data. Discussion, exercise questions, and lesson plans regarding boxplots are linked to the applet.
