statistics, the mid-range or mid-extreme of a set of statistical data values is the
arithmetic mean of the maximum and minimum values in a
data set, or:As such it is a measure of
central tendency. It is highly sensitive to outliers and ignores all but two data points; therefore it is rarely used in statistical analysis.A limited amount of experimental work on the efficiency of measures of central tendency for small samples by William D. Vinson reveals the following facts, where γ2 is the coefficient of
kurtosis: Values of γ2 Most efficient estimator of μ
-1.2 to -0.8 Midrange
-0.8 to 2.0 Arithmetic mean
2.0 to 6.0 Modified mean
