- This is !Statistix, version 1.02 (22 April 1995)
-
- Intro
- =========
- This program performs limited statistical analysis of data.
- It can contain two data banks only.
-
- It performs the following tasks.
-
- 1. Descriptive, data is available, about these two data sets.
- 2. A significance difference test can be performed on the two sets.
- 3. The first of these two sets can be analysed to find its' frequency
- distribution, and the resulting data can be saved as a CSV file , or
- displayed as a histogram, which can also be displayed as a drawfile.
-
- Starting
- =========
- Double clicking on the icon bar or dragging a suitable
- CSV file to it opens the main window.
-
- Four methods are available for data input, being accessed from the four
- large slab icons towards the top of the windows.
-
- 1. Dragging in CSV or suitable text files.
- 2. Data can be entered from the keyboard.
- 3. Random numbers can be generated from the program
- 4. Random numbers, being bunched nearest to their mean can be generated.
-
- Having entered at least one set of data by one of the above means, a window
- opens for each set of data. The program won't allow you to load more than
- two files.
-
- The data windows, each have a menu that allows you to perform the
- statistical operations on them. You can also save the files in CSV format.
-
- Significance Difference Tests
- ==============================
- These can only
- be performed when each of the data banks is occupied. The tests are suitable
- for comparing small data sets. A window displays the confidence limits that
- the sets show differences.
-
- Paramaters
- ==========
- Descriptive variables such as mean and standard
- deviation are displayed.
-
- Frequency Distribution
- ======================
- This can only be performed on
- data set 1. The program works out some sensible limits for the sets it is
- counting. These can be overidden, from the Frequency Distribution Window,
- but you will not be able to choose limits that give more than 20 divisions.
-
- Uses
- =====
- There is a good set of statistics packages on RiscOS, and this
- one is limited. The components were originally conceived on the Beeb for use
- in school. The significance tests were for comparing small sets of data.
- This included studying areas of different facing walls for lichen cover.
-
- The histograms were used to enter such measurements as the height of pupils.
-
- Disclaimer
- ==========
- I cannot in any way guarantee the accuracy of the
- routines here. I would be happy to hear from any one finding problems, and I
- may even be able to include other statistical routines if anyone asks for
- them.

- EventShell
- ==========
-
- Thanks to Paul Hobbs for his very useful !EventShell System.
-
- This application uses the library of routines of the above name, which
- provide an easy way of genereating a Wimp Program.
-
- I recommend this system which can be obtained from APDL or other PD
- Libraries.
-
- This program has been written using the routines supplied with the EvntShell
- library which is copyright Paul Hobbs. The library routines may be
- distributed subject to the following conditions:
-
- You have permission to use any part or the whole library in a project you
- intend to place in the public domain, as long as I am fully credited (via
- the inclusion of this file in the program documentation). If you wish to use
