... add statistics to your data: Use free-of-charge MS-Excel-tools to analyse your data
For statistical consulting and seminars, I have programmed few tools in MS Excel.
You can download them here free of charge. They should work with all MS Excel-Versions.
The files contain a short description of methodology, and an example.
Please notice: I try to program the tools to deliver valid results. They were checked to be free of viruses etc.
However, I cannot guarantee validity and free-of-virus status. There is no liability in terms of validity of results and free-of-virus state of the tools.
Most of tools are described etc. in German. I try to translate the tools step by step. If you need an English version, please send me an E-mail. I will use your request to setup an English version.
