I mean the median.
From Wikipedia...
For example, if *a* < *b* < *c*, then the median of the list {*a*, *b*, *c*} is *b*, and, if *a* < *b* < *c* < *d*, then the median of the list {*a*, *b* , *c*, *d*} is the mean of *b* and *c*; i.e., it is (*b* + *c*) / 2.
In the preceding paragraph wikipedia isn't that strict: 'the median is then usually defined to be the mean of the two middle values', and tor is unusual. :-)
