variance
A deviation or lack of agreement between different things or conditions.

'Varianz' (variance) belongs to the word family of 'variieren' (to vary, change, alternate) and 'die Variante' (the variant). All of these words have the Latin root for 'different' or 'changeable'.
Die Preise für das Produkt variieren je nach Anbieter stark.

You can recognize the statistical meaning from words like 'Daten' (data), 'Mittelwert' (mean), or 'berechnen' (to calculate). The more general meaning of deviation is often used in connection with comparisons of opinions, reports, or statements.
Für die Studie müssen wir die Varianz der Messwerte berechnen.
For the study, we have to calculate the variance of the measured values.
In statistics, 'Varianz' (variance) is a precisely defined technical term. Outside this field, the word is rarely used with this precise mathematical meaning.
Im Statistikkurs lernen wir, wie man die Varianz und die Standardabweichung ermittelt.
In statistics class, we learn how to determine variance and standard deviation.
In the meaning of 'Abweichung' (deviation), the preposition 'zwischen' (between) is often used to name the things that do not agree: 'die Varianz zwischen A und B' (the variance between A and B).
Die Varianz zwischen dem Plan und der Realität war überraschend groß.
The variance between the plan and reality was surprisingly large.

Variation and Varianz can refer to differences and dispersion among data values. Variation describes the observed variability in general, while Varianz is a calculated measure of dispersion around the mean. Use Variation in a general description and Varianz for a specific statistical measure.
Die Varianz der Messwerte um ihren Mittelwert wurde anschließend berechnet.
The variance of the measurements around their mean was then calculated.
Die Variation der Messwerte ist in dieser kleinen Gruppe deutlich sichtbar.
The variation in the measurements is clearly visible in this small group.
