Nature will affect your pokemon's stats. It's not big change. 
For example

Trecko: Lonely...It's attack has been enhanced but it's defenseis quite low..it can be enhanced 
through stat enhancers such as Calcium,Iron,Protein etc.

Take note that nature can play a big deal if your an EV trainer..In NetBattle..every aspect of your pokemon must
be good. Nature is a big component for this battle. Some kids don't take the nature seriously.But we experts
are fond of being the best therefore every pokemon's nature is very crucial to us. Especially if it's our favourite
pokemon.
