This tutorial, created by Thomas W. MacFarland of Nova Southeastern University, explains the theory and use of the Kruskal-Wallis test and demonstrates it with an example on exam scores, homework scores, and project scores. Data sets are provided in both SPSS and Minitab code. This is a great refere more
This collection of datasets from the University of Massachusetts at Amherst is categorized by topic. Each dataset and its description are in text format. Topics include: analysis of variance, analysis of covariance, cluster analysis, contingency table analysis, correlation analysis, descriptive stat more
This activity, created by faculty members at the University of Virginia, addresses the concept of sample space. It provides a multi-step procedure and three handouts, which accompany the activity. The activities are either basketball or badminton lesson plans, for a gym teacher. Students are divided more
Created by Joan Garfield of the University of Minnesota, this activity provides students with 24 histograms representing distributions with differing shapes and characteristics. By sorting the histograms into piles that seem to go together, and by describing those piles, students develop awareness o more
This site, presented by the Department of Statistics at Yale University, gives an explanation, a definition and an example of sampling in statistical inference. Topics include parameters, statistics, sampling distributions, bias, and variability. Overall, this is a great resource for any mathematics more
This library contains a plethora of downloadable applets and the components of the applets for use by teachers and students of probability and statistics. These objects (both executable files and source code) can be downloaded, modified if desired, and reused.
This Web site is a course in statistics appreciation; i.e., acquiring a feeling for the statistical way of thinking. It is an introductory course in statistics that is designed to provide you with the basic concepts and methods of statistical analysis for decision making under uncertainties. Materia more
This applet, created by David M. Lane of Rice's Virtual Lab in Statistics, illustrates many features of a two-factor analysis of variance. Allows the user to adjust the group size and group means. Gives output of ANOVA table and a Venn diagram showing how the sum of squares total is divided among SS more
This is a downloadable software simulation of light emitting diode simulation. It demonstrates band gap theory and shows how a single photon is created. Users can adjust the input voltage to allow the recombination of the electrons and holes. Note what happens to the photon when you adjust the band more
This simulation-based laboratory activity allows the student to practice several types of graphs and explore the types of information that we can collect from graphs. Coverage include exploration of linear, non-linear and logarithmic relationships as well as an error analysis.
