do you mean boosts from added effects (like fiery dance's sp. attk raise) or boosts from swords dance or both?

That would be both. This is why I don't specify XD I mean both

Answer 1

• The moves that raise the most stats are ancientpower, silver wind, and ominous wind. They have a 10% chance to raise attack, defense, special attack, special defense, and speed.
• The moves that raise a single stat the highest is belly drum (+6 attack)
• Moves like swords dance/quiver dance/etc have the highest chance to raise a stat but for damaging moves it is flame charge(100% chance to raise speed), and after that it is charge beam with 70% chance to raise special attack.
• The move that decreases the most stats is v-create which decreases special defense, defense, and speed.
• The moves that decrease a stat the lowest are shell smash (-2 in defense and special defense(self-inflicted)), memento( drops opponents attack and special attack by two stages), acid spray(drops opponent special defense by two stages), and overheat/leaf storm/draco meteor/psycho boost reduce special attack by two stages(self-inflicted).
  I believe thats it. I will keep searching to see if I find anything else.
• The move with the highest chance to inflict a status problem by side effects is inferno (100% chance to burn), and zap cannon(100% chance to paralyze). But of course moves like thunder wave/will-o-wisp/toxic/etc. also have 100% chance.
