VuStat is a program with a wealth of possibilities to illustrate ideas in statistical education. VuStat is the statistical package for secondary education for students and teachers. It comes with data and simulations to enhance teaching statistics and probability or students from the age of 12. VUStat consist of seven different modules. Download pamphlet pdf.

Data analysis enables you to make the usual tables and graphs It has some advanced options, but the main purpose is to make the analysis of data easier to understand for student who is neither a statistics expert nor a computer whiz kid. The selection and splitting of the data is made straightforward. You can download the vustat-file dndeng.vus which contains the data of more then 50000 students. This is a nice dataset to show the dancing boxplots in the graph menu.  

Dataplot enables students to make graphs of data. Dataplot is a small environment, especially useful for analyzing frequency tables. Traditionally much teaching concentrates on frequency tables. Dataplot allows the students to do more then drawing graphs, it lets the student concentrate on the more sensible task of comparing and interpreting data.

Trees A tree diagram visualizes a probability tree from different viewpoints. Both a regular tree and a free tree are possible to construct. The module Urn shows the probabilities when drawing balls from an urn with or without replacement. For economics and business students there are decision trees and game trees. For those interested in advanced financial mathematics, price calculations of call and put options are also included.

Simulation.  This part of the program lets the Student can run different simulations where he or she can interpret the data. This includes classical simulations such as throwing coins and dice and many more simulations. 

Distributions. The binomial, Poisson, t-distribution and normal distributions can easily be manipulated by students. The central limit theorem is demonstrated with skewed and normal dice.

Hypothesis. The difficult subject of testing a hypothesis is made comprehensible with a structured setup to formulate the test and the sample. The p-value is shown so that the student can easily see what is going on. The power of the binomial test is visualized. Our conviction is that pictures that can be manipulated are helpful to give real understanding to most students prior to making the calculations. 

Probability. Simulations and theoretical values are for example presented in a Galtonís grid. In module Grid, the number of routes in a grid is shown. Students are able to handle and understand absolute frequencies much better than they do with relative frequencies. There is also a module which introduces systematic counting. We illustrate with numbers or colours and in trees and tables concepts like variations, permutations and combinations. Combinatorics has a strong link to probability. We also show how Markov processes work and they are shown as a diagram, matrix, or graph.

Many parts of the program can be turned off so that the student is not confronted with too much complexity at any given stage.
