interkvartiilivahemiku
Interkvartiilivahemik, often abbreviated as IQR, is a statistical measure that represents the range of the middle 50% of a dataset. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). The first quartile is the value below which 25% of the data falls, and the third quartile is the value below which 75% of the data falls. Therefore, IQR = Q3 - Q1.
The interquartile range is a robust measure of statistical dispersion, meaning it is less affected by extreme
In practice, the IQR is often used in conjunction with the median to describe the central tendency
