Bob, no argument on the 122.55 number. Of course, I didn’t make the chart. In my writing, slides, and other media, I try to follow the rule of not presenting numbers that are more granular than that measured. Moreover, I am coming to the realization that rounding significantly can help with understanding more than unsupported strings of numbers. Does anyone care that 31.5 or 34.76 percent of Americans are obese? Better to say one-third in most cases, I think.

I sometimes think to recreate such charts, but honestly don’t have time.

As for the stopping at 75, I don’t disagree. The study authors should show us the whole picture (if they have it).

Thanks for your insights. The chart is indeed suboptimal, but the problem is common, even in really good publications.

With appreciation,

Michael
