To consider, represent, or cause to appear as larger, more important, or more extreme than is actually the case; overstate.
As you point out, the weighted difference is ~17 which you can clearly see in the data. Increasing this by a full point is quite significant and most people do not even have the intuition that it is even mathematically possible to increase 17 to 18. This is why we teach Simpson's paradox. I also posted the data so people could come to their own conclusion. Just because you use a definition of exaggeration to mean some nonsensically large difference, that does not make my claim misleading.
