Varianciája
Varianciája is a Hungarian term that translates to "its variance" or "their variance" in English. It is a statistical concept used to measure the spread or dispersion of a set of data points around their mean. In simpler terms, it tells us how much the individual values in a dataset typically deviate from the average value. A low variance indicates that the data points are clustered closely around the mean, while a high variance suggests that the data points are spread out over a wider range.
The calculation of variance involves summing the squared differences between each data point and the mean,
