The Min/Max values are calculated for a Pokémon at level 100. Maximum values are based on a beneficial nature, 252 EVs, 31 IVs. Minimum values are based on a hindering nature, 0 EVs, 0 IVs.
Tiers are calculated from the Pokémon with the highest available stat for that stat. Example: Blissey has the highest base HP at 255, so all tiers are divided by 6 from 255. Whereas the highest DEF is calculated from Shuckle at 230. This shows a better representation of where a Pokémon's base stat lies compared to the highest that stat can be. The length of the stat relative to the Tier also shows where it sits inside the Tier.

Pokédex entries:
Klefki
x-omega-ruby
These key collectors threaten any attackers by fiercely jingling their keys at them.
y-alpha-sapphire
It never lets go of a key that it likes, so people give it the keys to vaults and safes as a way to prevent crime.
sun
This even-tempered Pokémon has a habit of collecting keys. It will sneak into people’s homes to steal their keys.
moon
It inserts its horn into chinks in metal, absorbing metal ions. For some reason, it collects keys.
ultra-sun
Although it’s unclear why it collects keys, giving it a key makes Klefki very happy. However, it apparently only likes master keys.
ultra-moon
Long ago it lived in mines, but once the minerals that make up its diet became scarcer, Klefki began appearing in human settlements.
sword
This Pokémon is constantly collecting keys. Entrust a Klefki with important keys, and the Pokémon will protect them no matter what.
shield
Klefki sucks in metal ions with the horn topping its head. It seems this Pokémon loves keys so much that its head needed to look like one, too.
