Sind Ihre Daten normalverteilt?

Are your data normally distributed?
Abstract
For statistical evaluation a normal distribution of the data is often necessary and essential. Parametric tests require values like arithmetic mean and standard deviation (sd) and therefor a normal distribution. They are often way more precise compared to non-parametric ones. That's why one should always check whether the data features a normal distribution. If that is not the case a robust method is to use only non-parametric tests but there is also a way to make use of parametric tests. For this purpose, data transformation can be applied to achieve normality.
