medelriktning
Medelriktning, also known as median direction, is a statistical measure used to describe the central tendency of directional data. Unlike numerical data, which can be averaged, directional data, such as wind direction or compass bearings, are circular and require a different approach to find a central value. The median direction is the angle that minimizes the sum of the absolute deviations from all other angles. It is particularly useful in fields such as meteorology, oceanography, and geology, where directional data is common.
To calculate the median direction, the data is first converted to a common scale, typically in degrees.
Medelriktning is a robust measure of central tendency for directional data, as it is not affected by
