In a sentence or two, how would you describe these distributions (Hint: focus on the difference between the mean and the median for each distribution)?
Run some histograms to further explore the shapes of these distributions. Vary the intervals/ bin sizes to get the best description of the pattern you can.
pwhite
pblack
phisp
Attach your histograms to your lab when you hand it in (with a title etc), and on each one, describe the pattern you observe. Why did you choose the number of bins in each histogram?
Since the descriptive analysis above shows that the distributions we want to analyze are highly skewed, in what follows, we look at ways to focus our comparison of different parts of the distribution.
white black hisp nonwhite
pwhite pblack phisp pnonwhit
