Just a few clicks to reveal the absolute truth or rather “do not trust any statistics…”?

`Evaluation strategy´ is the magic word in Q-DAS software products qs-STAT, solara.MP, destra and the CAMERA tools. This article tells you what an evaluation strategy actually is and how you can design it.

Before dealing with the selected topic, I first want to give a warning. Please note that I wrote parts of the text with a slight twinkle in my eye but only parts of it, not the whole text.

Critical fellows only know a single answer to this question: My own strategy is the most correct.

This is no surprise because statistics is a branch of mathematics. `The cognition of the reason through construction of conceptions is mathematical´, said Immanuel Kant. He also stated that no natural science contained more truth than `pure mathematics´. But why did M. L. H. Kessel alias Hans Bruehl dare to say statistics was `the fairy tale of rationality´? And there are even more irreverent quotes we avoid here for reasons of youth protection!

Where do these issues we have with statistics actually come from?

The first aspect you should know is that there are two different types of statistics – descriptive ...
