It can be intimidating to read across statistical text books, trying to find the correct statistical analysis for a study. And since statistics is such a large field, it is often difficult to understand when to use which analysis or test. We understand that scientists want to conduct appropriate statistics, but their focus is science and not statistics. Therefore, we developed GSS – Guided Statistics for Scientists, a statistical software and support system, which helps scientists to quickly find and conduct the correct analyses. Nevertheless, GSS is a powerful software with professional capabilities, offering many options when needed.

Derived vs original data?
When presenting the findings of a study people often don’t show the original data that were measured, but they create so called ‘derived data’.
