It isn't stated, but here's how it's done. Every stat has a primary rune.
Marks specialyze in offence, seals in defence, glyphs in magic.
So runes that give armor penetration would be primary marks (red), health is primary for seals and AP is primary for glyphs.
If you're interested in a stat just check all the runes to see which one gives the most, for the most stats it should be easy to see if it's offence, defence or magic.
Quintescences specialyze in Utility, but they give fairly high bonuces from every stat.
