It focuses on the t-distribution, the assumptions for using it, and graphical displays. The activity also focuses on how to interpretations a confidence interval, a p-value, and a hypothesis test. 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=439749 This tool allows students to test their knowledge of levels of measurement in game-like enviroment similar to "Who Wants to be a Millionaire.״ http://www.merlot.org/merlot/viewMaterial.htm?id=238910 This activity explains the important features of a distribution: shape, center, spread, and unusual features. It also covers how to determine the difference between mean and median, and their respective measures of spread, as well as when to apply them to a particular distribution. Graphical displays such as: histograms and boxplots are also introduced in this activity. The corresponding data set for this activity is found at the following web address: http://www.causeweb.org/repository/ACT/food.txt http://www.merlot.org/merlot/viewMaterial.htm?id=238914 This activity stresses the importance of writing clear, unbiased survey questions. It explore the types of bias present in surveys and ways to reduce these biases. In addition, the activity covers some basics of surveys: population, sample, sampling frame, and sampling method. http://www.merlot.org/merlot/viewMaterial.htm?id=90873 Modules, exercises and links for teaching students how to utilize data bases available on web. http://www.merlot.org/merlot/viewMaterial.htm?id=238892 This activity will allow students to familiarize themselves with technology and its use in calculating marginal, conditional, and joint distributions, as well as making conclusions from these tabular and graphical displays.
