The QS matrix has been found to offer the advantages of excellent diagonal separation and stereo compatibility, and although the adjacent speaker separation is only 3 dB, this symmetrical distribution produces more stable quadraphonic images.

More generally one can raise the data to a power " p " in order to fit symmetrical distributions to data obeying a distribution of any skewness, whereby " p " 1 when the skewness is negative.
13.
It is customary to transform data logarithmically to fit symmetrical distributions ( like the mode, and with a right hand tail that is longer than the left hand tail ), see lognormal distribution and the loglogistic distribution.

To discourage Melkor from assailing Aman, they thrust the continent of Middle-earth to the east, thus widening Belegaer at its middle and raising five major mountain ranges in Middle-earth which adopted a relatively symmetrical distribution, namely the Blue, Red, Grey, Yellow Mountains and the Mountains of the Wind.
15.
To fit a symmetrical distribution to data obeying a negatively skewed distribution ( i . e . skewed to the left, with mean < mode, and with a right hand tail this is shorter than the left hand tail ) one could use the squared values of the data to accomplish the fit.
16.
In a non-symmetrical distribution i . e . mean < median < mode or mode < median < mean, it is statistically impossible for the majority of people to be above average when the average is taken to be the median, as the median represents the 50th percentile, or the midpoint of the data.
