Add some basic statistics with Panda

[ellenkoenig]

Idea: Add some more statistical processing such as averages, median, percentiles, correlations to follow after the intro to pandas using the "radish voting" example from here: http://opentechschool.github.io/python-data-intro/core/survey.html

Would this include an intro to Pandas or would two sections make more sense: "Intro to Pandas and data frames" and "Basic statistics with Pandas"? I tend to lean more towards the bite-sized-chunks strategy. Too much on one page and you lose the overview and get frustrated. I've added a related issue.

I agree with you, and I in fact tried to say the same thing. I guess I was not clear. The part about "re-doing the radish analysis in pandas" is supposed to be an intro to pandas and data frames. The intro to stats with pandas would be the next section as I envision it.

I guess splitting the two sections into two issues is a better approach. I will move part of my idea there so that this issue here only covers the stats section.
