summarize these 16 values according to a defined scale

gistfile1.txt

Goal: To summarize these 16 values and rate it on my scale. My first inclination is to use the median value(80). I didn't think the average is accurate because sometimes the data can be highly skewed.

scale: {40: 'extra low', 80: 'low', 160: 'moderate', 240: 'high-moderate', 320: 'high', 400 : 'extra high'}

>>> pd.values()
[160, 80, 80, 120, 240, 400, 80, 80, 400, 240, 80, 80, 160, 80, 80, 80]

>>> numpy.std(pd.values())
107.9062092745362

>>> numpy.mean(pd.values())
152.5

>>> numpy.median(pd.values())
80.0
