Which PHB are you referring to?
The 5e PHB (p13) has this:
Building Bruenor, Step 3
Bob decides to use the standard set of scores (15, 14, 13, 12, 10, 8) for Bruenor's abilities. Since he's a fighter, he puts his highest score, 15, in Strength. His next highest, 14, goes in Constitution. Bruenor might be a brash fighter, but Bob decides he wants the dwarf to be older, wiser, and a good leader, so he puts decent scores in Wisdom and Charisma. After applying his racial benefits (increasing Bruenor's Constitution by 2 and his Strength by 2), Bruenor's ability scores and modifiers look like this: Strength 17 (+3), Dexterity 10 (+0), Constitution 16 (+3), Intelligence 8 (-1), Wisdom 13 (+1), Charisma 12 (+1).
