This site, presented by the Department of Statistics at Yale University, gives an explanation of, a definition for and an example of confidence intervals. It covers topics including inference about population mean and z and t critical values. The page nicely blends graphs and visuals, along with tex more
This site gives an explanation, a definition of, and an example using comparison of two means. Topics include confidence intervals and significance tests, z and t statistics, and pooled t procedures. Overall, this is a nice presentation of these topics for any mathematics classroom.
This applet demonstrates the partitioning of sums of squares in analysis of variance (ANOVA). It includes some sample values and allows the user to make adjustments, which then shows the new values in the ANOVA table. Also contains an exercise set. Overall, this is a nice resource for any mathematic more
Created by Leonard Lipkin and David Smith for the Connected Curriculum Project, the purpose of this module is to study a standard model of population growth in a constrained environment. This is one lesson within a larger set of learning modules hosted by Duke University.
This compendium, created by Dr. Michael P. McLaughlin, describes distributions appropriate for the modeling of random data. The number of distributions, fifty-six, is large, including: continuous distributions (30), symmetric (11) and skewed (19), continuous binary mixtures(17), discrete distributio more
This article, created by Gary Smith of Pomona College, discusses a project-based approach to teaching statistics. The article focuses on the team aspect of learning, it introduces concepts such as: working with data, learning by doing, learning by writing, learning by speaking, and authentic assessm more
Created by Alan Heckert and James Filliben, this lesson, part of the National Institute of Standards and Technology (NIST) Engineering Statistics handbook, contains links to web pages which have tables of values for various distributions. More specifically, these distributions consist of: the cumula more
Created by Alan Heckert and James Filliben, this chapter of the National Institute of Standard and Technology (NIST) Engineering Statistics handbook ÂÂdescribes the terms, models and techniques used to evaluate and predict product reliability. It contains an introduction, discussions on the as more
SalStat is an small application for the statistical analysis of scientific data (with a special concentration on psychology). It can already do 18 kinds of descriptive statistics, t tests (paired, unpaired and one sample), 3 kinds of correlations linear regression and point biserial tests, and singl more
This applet graphs histograms and stemplots. It additionally calculates measures of center and measures of spread for data sets from the text "Practice of Business Statistics."Â There are ten stock sets of data. These are very useful for education purposes as students can practice on each one of more
