The trimmed mean is useful for obtaining a measure of location when some extreme values may distort the estimate if they were taken into account. The 50% trimmed mean is also called the GetMidMean().

percent must be expressed as a percentage. The 10% trimmed mean corresponds to a value of 10, not 0.1.

The 10% trimmed mean is one of the measures of location used by LeveneTest.
