It could be a case where 1 7-Eleven car crash per day is the median, but not the majority, with 0 and 2 or more combined being more than 50%, so they mean (but communicate poorly) that most days have 1 or more cars crash into 1 or more 7-Elevens, but they couldn’t say that most days have 1 car crash into a 7-Eleven. The only additional information that that would give above simply reporting the 1.14 average is that it’s not highly concentrated on a few days, like if 300 of the annual car crashes into 7-Elevens all happened on 7/11 when people jostle over free slurpees.
In short, “average” has too many meanings for its average use.
This makes for way better TV than if the camera simply worked. It’s a mistake that a human would probably never make, and definitely not persist in making.
