VUstat is more than just a program with which to perform statistical calculations or produce statistical diagrams. It incorporates sections relating to Data analysis and probability, which include explanations and demonstrations.
On many screens you will see the info button. Clicking on this will give you information specific to that screen.
Data Analysis
Using VUstat allows you an easy way to do statistical research. Not only with ready-made files, you can also create a survey and enter the data in VUstat. You can create all kinds of diagrams with the data.
Dataplot
With Dataplot you can create diagrams of frequency tables. These may be either simple diagrams or three-dimensional diagrams. You can adapt these diagrams.
Probability
This section has several options that are useful in counting problems and probability problems.
Trees
A tree diagram is a useful tool for dealing with all sorts of counting and probability problems. There is a section on the use of trees in economic applications.
Simulations /Applied simulations
With VUstat there are various experiments: for example, throwing a coin, and simulation games. The results are produced as a table or chart and in some cases as a file that you can analyze: see the Data analysis section.
Make Data
Three modules, allowing you to create your own data
Probability distributions
Here you will find an electronic tables book. Next to the table you can see the graph of the probability distribution, derived from the values in the table.
There are four distributions: binomial, poisson, normal, and hypergeometric.
The Plots of distributions option allows you to present different distributions simultaneously in one figure plotting. Additionally, this category provides demonstrations of the Central limit theorem.
Testing hypothesis
This section explains the testing of a hypothesis by means of a chart. You see how the test works. The conclusion of the test is formulated separately and can be printed or read in a text file. There are binomial test, t-test and z-test. Additionally, this section includes demonstrations of confidence intervals.
Profiles
VUstat is designed in such a way that it can be tailored to the learner/user who is working with the program. In this section you can fine-tune the program. You can set "masking" on options and menu items: they are then no longer visible. A profile is a combination of settings. A profile-button on the main menu screen or Ctrl-P gives access to the Profiles section.
