Quoting:
t[len(t)/2] is the median not the mean. The mean is the sum of the values divided by the number of values.
The fix is to either properly calculate the mean (which it looks like it was doing prior to 07fab0f9b46416c5c789c6d2fa0b503b8cff3f70 ) or rename the variable and the associated stat to 'median'.
Copying https://github.com/bitly/gographite/issues/9 here because it's important. The summary statistic is either wrongly calculated or wrongly labelled.
