Vehicles excluded from graph?
Some vehicles appear to be being excluded from graph of mpg by vehicle - For Subaru Outback, my vehicle is being excluded from the graph - the MPG for mine is 45mpg (UK) which would appear to be an outlier, but is because it is a diesel.
I assume that this is because the graph is being limited to a number of standard deviations, as I see that one vehicle with an mpg of 19 is also excluded.
However, I think that the logic behind showing only a certain number of SD is flawed, as having diesel and petrol models on the same graph mean that it is not a normal distribution. On the Fiesta model, you can clearly see that there is a dual peak distribution, as you have a substantial number of diesels, and so the full range is shown. However, with the Outbacks, there only appear to be 2 diesel vehicles, so the secondary peak is not apparent.
Cheers,
Joel
