The Friedman test analyzes whether there are statistically significant differences between three or more dependent samples.
The Friedman test is the non-parametric counterpart of the analysis of variance with repeated measures.

Regression analyses are divided into simple linear regression, multiple linear regression and logistic regression. The type of regression analysis that should be used, depends on the number of independent variables and the scale of measurement of the dependent variable.

Wie ist der Aufbau eines Fragebogens? Was kommt alles in deinen Fragebogen rein? Am Anfang deines Fragebogens kommt der Einleitungstext, dann die Einstiegsfrage gefolgt von den Frageblöcken, dem Hauptteil des Fragebogens. Zum Schluss folgen dann noch die soziodemographischen Fragen und die Schlussfrage.

What is Hierarchical Cluster Analysis? And how is it calculated?
A hierarchical cluster analysis is a clustering method that creates a hierarchical tree of objects to be clustered (Dendrogram). The tree represents the relationships between the objects and shows how the objects are clustered at different levels.
