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.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).Simulations/Demonstrations in Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=75489
This Virtual Lab contains simulations for a variety of statistical concepts, including ANOVA, correlation, Regression, T-tests, Goodness of Fit, Histograms, etc. Each statistical topic can be searched and appropriate simulations or demonstrations are shown. Graphics that can be manipulated are shown, instructions are provided, and exercises are included. Links are also provided for definitions.Research Methods in Psychology
http://www.merlot.org/merlot/viewMaterial.htm?id=90013
This site has prepared and compiled content from numerous websites and resources to help students visualize and test statistical concepts. Also suitable for Research Methods course; learn research theories by participating in classic psychology experiments. Contains 70 simulations.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. The presentation is covered by a Creative Commons Attribution-Share Alike 3.0 License.Binomial Distribution
http://www.merlot.org/merlot/viewMaterial.htm?id=88102
Marbles bounce down an array of pegs. The resulting binomial distribution is displayed graphically in real time. A control panel allows the size of the array, and the probability of a bounce to the right to be varied.A short introduction has been added in the form of a series of multiple choice questions with instructions. Instructors wishing to author their own set of instructions and questions should contact the contributor.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.One-Way ANOVA (Interpretation and When to Use)
http://www.merlot.org/merlot/viewMaterial.htm?id=399988
Covers how to interpret the One-Way ANOVA results, why we use the ANOVA rather than several independent sample t test pair-wise comparisons. (Closed Captioned). Notes: [1] Captioning can be turned on/off using YouTube controls, [2] there is a Part A video that clearly outlines the research scenario (view at " target=״_blank״>http://www.youtube.com/watch?v=JPjMUeTMOwg).Correlation exercise
http://www.merlot.org/merlot/viewMaterial.htm?id=89758
This site presents an interactive correlation exercise designed for a research methods in psychology course. Students can administer and score any one of six on-line personality tests. Instructions for how to use the site to design and analyze a research project are available.Questionnaire Design and Surveys Sampling
http://www.merlot.org/merlot/viewMaterial.htm?id=76230
The site contains techniques and computer codes for questionnaire design, surveys sampling, and analysis.
