The skill and trainer skill picked above are the game's own — read straight off its official in-client line-ups on the Official Line-ups page. The Keepsake, Starcore and evolution materials are this line's own real items, from the game's own tables. Star Up's damage/mitigation numbers are the game's own published curve.

Each column is the species' own Min–Max range at its reference level — the exact spread the in-game Aptitude tab shows (an individual catch rolls somewhere inside it). See the Stat Rankings to sort the whole roster by any of these. Attack Speed is the Skill tab's Attack Interval: the seconds between automatic basic attacks, fixed per species, so lower is faster. Every basic attack deals the same damage per second, so a quicker one lands more hits rather than more damage, which is what on-hit effects care about. Each Swift stack speeds it up by 10% and each Paralysis stack slows it by 10%.
