scipy.stats.cmedian(a, numbins=1000)

Returns the computed median value of an array.

All of the values in the input array are used. The input array is first histogrammed using numbins bins. The bin containing the median is selected by searching for the halfway point in the cumulative histogram. The median value is then computed by linearly interpolating across that bin.

Parameters :

a : array

numbins : int

The number of bins used to histogram the data. More bins give greater accuracy to the approximation of the median.

Returns :

A floating point value approximating the median. :
