EVs are Effort Values. They allow you to enhance the stats of your pokemon. You get them for defeating a pokemon. The number and type of EVs you get are detemined by the type of pokemon you defeat. Every 4 evs in a stat is equivalant to 1 point towards that stat. They can contribute to a higher hp, speed, attack, sp attack, defense, and special defense, all based on what the pokemon you defeat is. Ex: A bidoof yeilds 1 HP EV. If you kill 4 bidoofs, you will get an additional HP point overall. The most EVs towards a stat you can have is 255, but that isn’t divisable by 4 (there would be 2 evs that wouldn’t contribute to up the stat as 4 EVs= 1 point) so it’s more practical to get 252 evs. You can get 510 EVs total. Certian items can add to(such as protien) / reduce (such as berries) the number of evs that you have in a particular stat. The pokevirus will give you double evs for each pokemon you kill.See more:http://pokemondb.net/ev

A pokemon’s nature will add and subtract how many points go to different statshttp://pokemondb.net/mechanics/naturesHope that was all clear enough.
