Most stat nummbers ingame arent clear at all. You got a def stat, and an armor stat. both simple numbers that cant really be calculated on the game damage. ( like how much % of damage is reduced by 100 def?)
You have a crit stat which affects what and how? 100 crit makes what critrate in % ? does it affect critdamage? (like 1,5x / 2x the base damage)
and so on...

Armor/10 = Damage Reduction (It is not a percentage reduction; Ie 1000 Defense = 100 damage)
Crit Rate amount does not change how much it crits; Damage on a crit is 1.5 10Crit=1% chance of Rate
Magic Attack/5 = Magic Damage Addition
Attack Damage = Attack Damage
Dodge Vs Accuracy = DodgeAccuracy/Dodge as a percentage
These are some general formulas.
It would be nice if they were better represented, but a little experimentation will tell you the answers
