Which Do You Meeeeaaannnnnn

On the Pittsburgh Pirates and the additional wild card:

↵↵Team president Frank Coonelly had Dan Fox, the Pirates’ statistical guru, build a computer model to illustrate the impact: The Pirates’ chance of making the playoffs increased 13 percent.

↵↵That almost certainly means 13 percent, and not 13 percentage points. So the article isn’t wrong. But a lot of people will interpret it wrong, because by and large people are terrible at handling “percent” vs. “percentage points”.
