| Aug 22, 2017 at 15:27 | comment | added | Nick Cox | The question is about a specific dataset; without access to that dataset it is hard to provide more than a few useful comments. So, voting to close as unclear (and unlikely to be helpful to any in its present form). | |
| Aug 21, 2017 at 14:05 | comment | added | Nick Cox | The groups don't seem similar any way when the maxima vary over several orders of magnitude. Again, we need more substantive information (than zero). Why blank out interesting detail? The data look too quirky for anyone to want to steal them. | |
| Aug 21, 2017 at 13:59 | comment | added | whuber♦ | Since the square root of an area is a length, which could be interpretable as a proxy for city diameter, one of the first things to consider is a boxplot of the square roots of the areas. The strong negative skewness of the logs and the (possible) positive skewness of the raw data both suggest using a power somewhere between $0$ and $1$ to re-express the data. You will still see a thirtyfold range of square roots, so you will want first to examine each boxplot on its own scale before plotting them side by side. (cc @NickCox) | |
| Aug 21, 2017 at 13:50 | comment | added | Nick Cox | Show the data directly for good advice. It's evidently somewhat quirky whatever you do. For example, logarithms have flipped the 5th group from right-skewed to strongly left-skewed. That's possible, but a little unusual. I note that in the simplest incarnation the log of a Pareto distribution is an exponential, and and so in that case log transformation is not expected to produce symmetric box plots. There's good reason for showing more detail when power laws are expected. | |
