Is there a baked-in Numpy/Scipy function to find the interquartile range? I can do it pretty easily myself, but mean() exists which is basically sum/len<
There is now an iqr function in scipy.stats. It is available as of scipy 0.18.0. My original intent was to add it to numpy, but it was considered too domain-specific.
You may be better off just using Jaime's answer, since the scipy code is just an over-complicated version of the same.
