In the median statistics, numerical values - e.g. from a chronological order - are rearranged in such a way that a data table is created in which Readings are sorted according to size (order statistics):
If the number of values is odd ( is an even natural number), the value in the middle is regarded as a characteristic value and referred to as the median or central value:
If there is an even number of in the table Measured values:
the mean of the two neighboring mean values is calculated (pseudomedian):
The median is a better measure of the most frequent value than the mean. This applies in all cases, but especially in the case of crooked or multi-peaked distributions.
