WISE's website organises a large amount of statistics resources available on the web into one central place. It also is home to a series of interactive, sequenced tutorials on key statistical concepts. The tutorials use dynamic applets that allow the user to explore relationships on their own. Guided exercises are designed to help the learner to take full advantage of the applets to gain a deeper understanding of the concepts and logic that underlie much of inferential statistics. On WISE, you can find WISE tutorials, WISE applets, excel downloads, teaching papers, quick guides, and publications.
Extract
"Objectives
Our goal is to provide easy entry to Internet resources that can be used in support of statistics education and applications. The site includes the following:
 interactive statistics tutorials
 answers to questions
 a jumpoff point for connecting to other resources for statistics on the Internet
Instructors will be able to utilize WISE in conjunction with their classes:
 to supplement their text assignments
 to provide common examples and practice problems, where students can receive immediate feedback
 to provide interactive demonstrations
Instructors can ask students to use WISE resources to supplement the textbook and classroom, or they can assign particular topics and questions for the students as homework."

Tutorials
Introductory Statistical Topics

Sampling Distribution of the Mean
 This tutorial teaches fundamental properties of sampling distributions of means such as accuracy of sample means, probability, and effects of sample size.
 Investigating the Central Limit Theorem
 Illustrates the basic principles of the Central Limit Theorem and enhances conceptual understanding of inferential statistics.
 The Logic of Hypothesis Testing
 This tutorial serves to introduce the logic of hypothesis testing using zscores.
 Statistical Power
 This tutorial introduces students to the concepts of statistical power and effect size.
 Correlation and Regression
 This tutorial focuses on statistical methods of describing the corelatedness of two variables, and howto use this information to make statistical predictions.
 The ttest Tutorial: Comparing Cultures
 In this tutorial, students gain experience applying descriptive and inferential statistics.
 Choosing the Correct Statistical Test
 This exercise poses different research scenarios and asks you what statistical test you would use to answer the research question of interest. An interesting approach to working with "real data."
Specialized Topics
 An Introduction to Signal Detection Theory
 In this tutorial, we illustrate the statistical basis of Signal Detection Theory (SDT) and demonstrate the similarities between SDT and Hypothesis Testing. SDT was developed in the psychological research community, but has become popular in fields such as clinical diagnosis and industrial design.
 Utility and Decision Making
 This tutorial focuses on statistical methods of decision making under uncertainty. The underlying model assumes bivariate normal distributions, distributions of N:N weights per group, and decision outcomes of varying utility. (Spring, 2003).
Applets (NB Many of these applets are no longer supported. Linked applets are working on the archived WISE website as of July 2020)
 Sampling Distribution of the Mean
 This applet teaches fundamental properties of sampling distributions of means such as accuracy of sample means, probability, and effects of sample size.
 pz Converter
 This applet converts probability values to z values and vice versa. The simple version converts only righttail pand z values. The graphic version allows the user to input lefttail p, raw scores, and the mean and standard deviation of the group of interest.
 Hypothesis Testing Applet
 This applet serves to introduce the logic of hypothesis testing using zscores.
 Statistical Power
 This applet introduces the concept of power and the relationship between power and effect size, alpha, and sample size.
 Confidence Interval Overlap
 This applet demonstrates how ttest p values are related to amount of overlap of confidence intervals.
 Confidence Interval Creation
 This applet illustrates how demonstrate how the population distribution and sample size influence confidence intervals.
 Correlation and Regression
 This applet demonstrates how the sum of squared deviations is affected by the fit of the regression line to data points.
 Signal Detection Theory
 SDT is a statistical theory of decision making which summarizes a person's ability to discriminate between different classes of items based upon their correct decisions (Hits) versus their Errors (False Alarams). The applet also plots the ReceiverOperating Characteristics.
 Classification, Utility, and Decision Making
 An applet which assists in determining group membership based upon test performance, utility of correct and incorrect classification, and population base rates.
 Bootstrapping
 This applet can be used to help visualize the resampling method of bootstrapping. "Resamples" from an original sample can be taken one at a time, or 10,000 at once, ultimately providing a 95% confidence interval for the population mean or median.
 Confidence Interval Game
 This applet was designed to provide a fun method to learn about p values. Challenge yourself and see how well your estimates match with the real value.
