mediaanwaarde
Mediaanwaarde, often translated as median value, is a statistical measure representing the middle value in a dataset that has been ordered from least to greatest. To find the median, all the numbers in a set are arranged sequentially. If there is an odd number of data points, the median is the single number in the exact middle. For example, in the set {2, 5, 8, 11, 14}, the median is 8. If there is an even number of data points, the median is the average of the two middle numbers. For instance, in the set {3, 6, 9, 12, 15, 18}, the two middle numbers are 9 and 12, so the median is (9 + 12) / 2 = 10.5.
The median is a robust measure of central tendency, meaning it is not significantly affected by extreme
