High Quality Content by WIKIPEDIA articles! In statistics, the trimean (TM) is a measure of a probability distribution's location, defined as a weighted average of the distribution's median and its two quartiles. Like the median and the midhinge, but unlike the sample mean, it is a statistically resistant L-estimator, having a breakdown point of 25%. The trimean goes back to Arthur Bowley. It was discussed by statistician John Tukey in his 1977 book which has given its name to a set of techniques called Exploratory data analysis.
