One of the most frustrating aspects of car audio is noise in the system. Unlike home audio systems, car audio systems have many sources of noise to deal with. Here's a few of the most common noises found in car stereo and how to fix or avoid them.
While the mean of a set of values minimizes the sum of squares of deviations and the median minimizes the average absolute deviation, the midrange minimizes the maximum deviation (defined as max | x i â m | {\displaystyle \max \left|x_{i}-m\right|} ): it is a solution to a variational problem.
In other words, the midrange takes into account the zero-values that exist between minimum and maximum as coincidental, and assumes the possibilities of values collected evenly spaced. The disadvantage of the midrange, however, is the fact that it fails to weight the data collected.t is a relatively straight-forward measure of central tendency. It is merely the arithmetic mean amongst the data subset including only the minimum and maximum values of the larger set, ignoring all intermediate values of the set.
