4434Sampling Distribution of the Mean Tutorial
https://www.merlot.org/merlot/viewMaterial.htm?id=82347
This tutorial will help you determine how accurate a sample mean is likely to be, and how this accuracy is related to the sample size. Brief reviews of the normal distribution and the Central Limit Theorem are included as supplemental materials.Thu, 14 Oct 2004 00:00:00 -0700Confidence Interval for a Mean
https://www.merlot.org/merlot/viewMaterial.htm?id=79518
This Java applet tutorial provides a series of word problems on determining confidence intervals. Each problem prompts the user to input the steps for determining a confidence interval for the mean. Hints are provided whenever the user enters an incorrect value. Once the steps are completed, a statement summarizing the interval obtained is displayed. The applet is supported by an explanation of the steps in creating confidence intervals..Mon, 9 Jun 2003 00:00:00 -0700Adventures in Statistics - Free Learning Episodes
https://www.merlot.org/merlot/viewMaterial.htm?id=84257
Adventures in Statistics is a free online learning resource designed to teach students statistics. Comprised of five lively and engaging learning episodes that are each 10 to 15 minutes, students are taken through storylines, exercises, assignments and more.At the heart of these modules are fun situations, quirky characters, and animated diagrams that put students at ease and facilitate their ability to grasp concepts covered in an introductory statistics course.In these modules, students will test squirrel intelligence, help aliens decide whether or not to invade Earth, help a 1970’s disco king decide if it’s profitable to open a record store, and more.Fri, 8 Jul 2005 00:00:00 -0700Hypothesis Test for a Mean
https://www.merlot.org/merlot/viewMaterial.htm?id=79516
This Java applet tutorial prompts the user to input the components of a hypothesis test for the mean. Hints are provided whenever the user enters an incorrect value. Once the steps are completed and the user has chosen the correct conclusion for accepting or rejecting the null hypothesis, a statement summarizing the conclusion is displayed. The applet is supported by an explanation of the steps in hypothesis testing and a description of one-tailed and two-tailed tests.Mon, 9 Jun 2003 00:00:00 -0700Hypothesis Test for a Proportion
https://www.merlot.org/merlot/viewMaterial.htm?id=79517
This Java applet tutorial prompts the user to input the components of a hypothesis test for a proportion. Hints are provided whenever the user enters an incorrect value. Once the steps are completed and the user has chosen the correct conclusion for accepting or rejecting the null hypothesis, a statement summarizing the conclusion is displayed. The applet is supported by an explanation of the steps in hypothesis testing and a description of one-tailed and two-tailed tests.Mon, 9 Jun 2003 00:00:00 -0700Introduction to Minitab
https://www.merlot.org/merlot/viewMaterial.htm?id=83045
This laboratory introduces students to the basics of the Minitab software. Students make use of a basic example (water consumption and temperature) to introduce students to manipulation of data, calculation of descriptive statistics, creation of histograms, boxplots and scatterplots. Students are asked to hand in the results they have produced. Accompanying documents give model solutions.Fri, 28 Jan 2005 00:00:00 -0800Statistics Every Writer Should Know
https://www.merlot.org/merlot/viewMaterial.htm?id=77058
This is a site that is meant to explain to writers what statistical data means. However, it is also a simple review, with examples, of statistical analysis from "Means" to "Sample Sizes."Sun, 23 Jun 2002 00:00:00 -0700Introduction to Hypothesis Testing -- The Z-Test
https://www.merlot.org/merlot/viewMaterial.htm?id=82334
This exercise will help the user understand the logic and procedures of hypothesis testing. To make best use of this exercise, the user should know how to use a z table to find probabilities on a normal distribution, and how to calculate the standard error of a mean. Relevant review materials are available from the links provided. The user will need a copy of the hypothesis testing exercise (link is provided), a table for the standardized normal distribution (z), and a calculator. The user will be asked several questions and will be given feedback regarding their answers. Detailed solutions are provided, but users should try to answer the questions on their own before consulting the detailed solutions. The end of the tutorial contains some "thought" questions.Thu, 14 Oct 2004 00:00:00 -0700Binomial Distribution
https://www.merlot.org/merlot/viewMaterial.htm?id=80319
This tutorial is designed to give students practice in calculating basic probabilities using the binomial distribution. The applet gives students short problem descriptions that require a binomial probability to solve. The user is then prompted to follow a step by step process to find the probability. Users must answer a step correctly before the applet will allow them to move onto the next step. The page also gives further exercises that allow the user to think about binomial distributions more deeply and gives a link to more detailed information about the binomial distribution. This tutorial is one of a number of easy-to-use statistics tutorials developed by Larry GreenSat, 29 Nov 2003 00:00:00 -0800An Introduction to Statistical Power
https://www.merlot.org/merlot/viewMaterial.htm?id=82345
This tutorial illustrates the relationship between statistical power and four features of the test situation. An applet allows the user to manipulate a factor and immediately see the effects on other factors.Thu, 14 Oct 2004 00:00:00 -0700
