    1. Measurements are variables that can be quantified. All data in the output above are measurements. Some of these measurements, such as state_percentile_16, avg_score_16 and school_rating, are outcomes; these outcomes cannot be used to explain one another. For example, explaining school_rating as a result of state_percentile_16 (test scores) is circular logic. Therefore we need a second class of variables.

      a more constrained. and thus more efficient way to do transformations on groupbys than the apply method. You can do very cool stuff with it. For those of you who know splunk - this has the neat "streamstats" and "eventstats" capabilities
