For this purposes of inciting hysteria or reinforcing a a preconceived argument, yes, always select the smallest sample possible, and make sure that the sample has data to support the conclusion one is trying to convey.
However in the larger scheme of things, all that cherry picking does is to discredit the argument. In this situation, it gets hot everywhere, not just in Phoenix, ergo a sample that includes the entire fleet universe is correct.
Now there has been an argument proposed that "Nissan botched its testing badly" for hot weather. I think not, and here is why. They have been doing hot weather testing for quite a while, but most likely using a 100 year high temp average for the hottest area of the US.
What is unusual is that this year has been special across the US with almost every historical high temp record shattered and new historical highs being set. My point is that it is the hottest this year, especially in the southern US, since records have been kept.
So the environment is outside the boundaries of normal 100 year heat ranges, and probably outside the range in which Nissan (and most other automobile manufacturers) designed to. But despite unprecedented historical extreme temperatures, the fact that only 0.0010625% of the fleet is experiencing questionable performance, despite that the vehicles are probably operating reliably in an environment that is outside their design envelope, is truly outstanding. The only complaint is that they need to be "filled-up" more frequently.
So despite all of the wailing and gnashing of teeth in this thread of a perceived travesty of trust, despite the historical extreme temperatures that not only Arizona but the world is experiencing this year, every LEAF, even in a cherry picked sample continues to start every day, no matter how hot it is, and perform with all its got.
