Guides & comparisons
Korrelation vs Kausalität: Was Daten wirklich zeigen
Two variables moving together does not prove one causes the other. This guide explains confounders, spurious correlations, and what evidence supports causation.
Konfidenzintervalle für Umfragen und Stichproben erklärt
A confidence interval estimates a population parameter with a margin of uncertainty. This guide explains what '95% confident' really means.
Mittelwert vs Median vs Modus: Welches Lagemaß?
The mean is the arithmetic average; the median is the middle value; the mode is the most frequent. Pick the right measure for your data shape.
Varianz vs Standardabweichung: Streumaße
Variance averages squared deviations; standard deviation is its square root, returning to original units. Both measure spread — SD is easier to interpret.

Frequently asked questions
- Stichproben- oder Populations-Standardabweichung?
- Varianz und Standardabweichung nutzen n − 1, sofern nicht anders angegeben.
- Kann ich Datensätze einfügen?
- Ja — komma- oder leerzeichengetrennte Werte.
- Welches Tool für Hypothesentests?
- Z-Score, dann z-Test oder t-Test.
