Statistical evidence is the kind of data people tend to look for first when trying to prove a point. That’s not surprising when you consider how prevalent it is in today’s society. Remember those McDonald’s signs that said “Over 1 billion served”? How about those Trident chewing gum commercials that say “4 out of 5 dentists recommend chewing sugarless gum”? Every time you use numbers to support a main point, you’re relying on statistical evidence to carry your argument.
