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 aged 12 to 18. VuStat consist of six different packages;
Statistics enables you to make the usual tables and graphs It has some advanced options, but the main purpose is to make it easy for the student who is not a statistics expert nor a computer wiz kid to analyze data. Selection, splitting of the data is made straightforward. 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. 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. Tree diagram visualizes a probability tree from different viewpoints. Simulations and theoretical values are presented in Galtons grid. In Grid the number of routes in a grid is shown. Urn shows the chances in an urn without replacement. In frequency grid ideas of Peter Sedgemeir are incorporated. Students do much better with numbers then with ratios. Call and put options are only of interest for advanced finance mathematics. Many parts of the program can be turned off so that the student is not confronted with too much complexity at any given stage. |
