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 we'll go over the hypotheses and the assumption. After that, I'll 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, we'll go over the formulas so you can better understand what happens in two-factor analysis of variance.

Welche Fragetypen gibt es in einem online Fragebogen? In diesem Video geht es um die wichtigsten Fragetypen, die du in deinem Fragebogen verwenden kannst. Wir besprechen jeweils, worauf du bei den Fragetypen achten musst und wie du sie auswertest.
Beginnen wir mit einem kurzen Überblick. Was sind die wichtigsten Fragetypen bzw. auf welche gehen wir ein? Da gibt es die offenen Fragen, Fragen mit einer Einfachantwort, Fragen mit Mehrfachantwort, Fragen mit Einfachantwort in Tabellen- bzw. Matrixform, Fragen mit Mehrfachantworten in Tabellenform und das semantische Differential.
Dieses Video hilft dir beim sauberen wissenschaftlichen Arbeiten und der empirischen Forschung.

![Normality test [Simply Explained]](https://i.ytimg.com/vi/AVketBmpUTE/mqdefault.jpg "Normality test [Simply Explained]
One of the most common requirements for statistical test procedures is that the data used must be normally distributed. For example, if a t-test or an ANOVA is to be calculated, it must first be tested whether the data or variables are normally distributed. This is done with a test of normality.
If the normal distribution of the data is not given, the above procedures cannot be used and the non-parametric tests, which do not require normal distribution of the data, must be used.
How do I test normal distribution?
Normal distribution can be tested either analytically or graphically. The most common analytical tests to check data for normal distribution are the:
1) Kolmogorov-Smirnov Test
2) Shapiro-Wilk Test
3) Anderson-Darling Test
For the graphical test either a histogram or the Q-Q plot is used. Q-Q stands for Quantile Quantile Plot, it compares the actual observed distribution and the expected theoretical distribution.
