Driving Skills vs. Population Density
It is also interesting that the ten states with the top population density average 80.35 for driving skills...while the states that are least densely populated average 85.2 for driving skills. A very significant 5 point difference!!
Also: The 6 states with the worst driving skills are also the 6 most densely populated states.
I took the top 15 and bottom 15 states by population density and came up with an equation for this phenomena.
y = 4E-05x2 - 0.0361x + 85.761
R^2 = 0.7236
This is actually a pretty good fit when analyzing real world situations. It would be a lot more convincing if R^2 were closer to .9.
