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.

![Two Factor ANOVA [without repeated measures]](https://i.ytimg.com/vi/8uUKkL7qgFk/mqdefault.jpg "Two Factor ANOVA [without repeated measures]
This video is about two-factor analysis of variance without repeated measures (2-Way-ANOVA). We discuss what you need two-factorial analysis of variance for and what the difference is between one-factor and two-factor.
Then well go over the hypotheses and the assumption. After that, Ill show you how to calculate the two-factor analysis of variance online with DATAtab, how to interpret the results, and we will discuss what the interaction effects are. Finally, well go over the formulas so you can better understand what happens in two-factor analysis of variance.
