Rephrasing it as 3 cans of soda doesn't make it sound good. 3 cans a day is quite a bit. It might be healthy (or not), but I'm pretty sure 1000 cans/year is well above average for the typical western nation.
I wouldn't be so sure about that. Soda drinkers I've met who are really into it tend to go through a few 12-packs a week. As a kid, I'd play Quake with a 2L of Cherry Coke each night, and I've known others who did the same with Mountain Dew. Live and learn, I suppose.
That's per capita; not everyone drinks soda. A liter per day could certainly be the average for soda drinkers.
I wonder what the difference is between mean and median in this case?
The standard deviation must be pretty high. There are lot people who drink almost no soda.
Well, I specifically called out typical western nations and not just the US. I see a lot of soda drinking in the US and never saw very much in Europe. I don't think American soda consumption is actually typical (or healthy).
