In statistics the trimean (TM), or '''Tukey's trimean''', is a measure of a probability distribution's central tendency defined as a weighted average of the distribution's quartiles: TM= \frac{Q_1 + 2Q_2 + Q_3}{4}
It gives twice as much weight to the median or second quartile Q_2 than the first and third quartiles.
