The table on page 13 indicates the Ranger as having a choice of Strength or Dexterity as their key attribute, but the ranger class writeup on page 113 says only Dexterity. One of these two are wrong, but which one?
(As an aside about table 13's content, I've already had multiple, different, confusions caused by the 'secondary attribute' column... I would ask for it to be removed entirely from the table. A notation somewhere that isn't a reference sidebar/table would be better, if you are including it at all, because then if someone is reading about them they are also reading the explanations for that information.)
