&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Effort values&#039;&#039;&#039; (abbreviated &#039;&#039;&#039;EVs&#039;&#039;&#039; and previously called &#039;&#039;&#039;Stat XP&#039;&#039;&#039;) are attributes which give bonuses to a Pokémon&#039;s stats and improve differently depending which Pokémon they defeat. These bonuses, in the form of effort points, are gained in addition to bonuses gained by increasing level. A Pokémon which increases in level using a [[Rare Candy]] instead of battling does not gain any EVs, making it weaker than a Pokémon who increases in level normally.&lt;br /&gt;
&lt;br /&gt;
Roughly speaking, defeating fast Pokémon increases Speed better than fighting slow Pokémon, defeating Pokémon with high hit points improves HP more than defeating Pokémon with low HP, and so on. For example, fighting 100 Machop will improve a Pokémon&#039;s attack stat more than fighting 100 Abra of the same level, whereas the Abra will improve the Special Attack stat more. For a list of the effort points that Pokémon give away on their defeat, see [[list of Pokémon by effort value yield]].&lt;br /&gt;
&lt;br /&gt;
Gaining effort points to increase desired EVs varies from being simple to complicated, depending on whether one wants their Pokémon to fully max out its stats or raise them to balanced heights.&lt;br /&gt;
&lt;br /&gt;
Effort values only appear in the [[version|main series]] Pokémon games, and are not present in the spin-off games, such as the {{pkmn|Mystery Dungeon}} series.&lt;br /&gt;
&lt;br /&gt;
==Generation I==&lt;br /&gt;
The EV system was introduced in [[Generation I]], where it was also called &#039;&#039;&#039;stat experience&#039;&#039;&#039; or &#039;&#039;&#039;Stat Exp&#039;&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
The [[Pokémon data structure in the GB|Pokémon data structure]] contains two EV bytes for each the five stats (HP, Attack, Defense, Speed and Special), starting at zero when caught and with a maximum EV of 65535 for each stat, however, maximum stats will be reached with only 64512 EVs. When a Pokémon is defeated, its [[base stats]] are converted to effort points and then added to the EVs. For example, defeating a {{p|Mew}} grants 100 effort points to each EV. (Defeating 646 {{p|Mew}}, therefore, will give a Pokémon maximum EVs in each stat.)&lt;br /&gt;
&lt;br /&gt;
EVs are factored into the Pokémon&#039;s stats when it levels up. Additionally, EVs are calculated into stats when a Pokémon is taken from Bill&#039;s PC; this is called the [[box trick]]. A Pokémon which reaches level 100 can continue to accrue EVs up to the maximum of 65535 in each stat, and use the [[box trick]] to have those EVs factored in.&lt;br /&gt;
&lt;br /&gt;
[[Vitamins]] add 2560 to one stat&#039;s EV, but cannot raise a stat above 25600. Unlike later games, the {{DL|Experience-affecting item|Exp. Share}} did not share EVs.&lt;br /&gt;
&lt;br /&gt;
At level 100, the formula for determining the stat difference between a Pokémon trained in that stat and an untrained Pokémon is:&lt;br /&gt;
&lt;br /&gt;
[[File:Statexp.png]]&lt;br /&gt;
&lt;br /&gt;
==Generation II==&lt;br /&gt;
EVs behave the same in [[Generation II]] as they did in [[Generation I]]. Both Special Attack and Special Defense share the EV for Special. The [[box trick]] can still be used.&lt;br /&gt;
&lt;br /&gt;
[[Generation II]] introduced the [[Pokérus]], a rare [[status condition]] which doubles the effort points gained in battle.&lt;br /&gt;
&lt;br /&gt;
==Generation III==&lt;br /&gt;
[[Generation III]] completely overhauls the effort value structure. Effort points are now separate values from the base stats. Defeated Pokémon give out 1, 2 or 3 &#039;&#039;&#039;effort points&#039;&#039;&#039; to a particular stat, depending on species (see [[list of Pokémon by effort value yield]]). However, in battles that do not give any experience (such as in the [[Battle Tower]] or if the Pokémon is level 100), Pokémon will not gain any effort points. At level 100, a Pokémon&#039;s stats will be one stat point higher in a specific stat for every four effort points gained in that stat.&lt;br /&gt;
&lt;br /&gt;
Pokémon are limited to a total of 255 effort points per stat, and 510 effort points in total. Maximum stats will be reached with only 252 EVs in a stat, however.&lt;br /&gt;
&lt;br /&gt;
[[Vitamin]]s add 10 effort points, but cannot raise a stat above 100, or raise the total above 510. A new vitamin, {{DL|Vitamin|Zinc}}, enhances Special Defense.&lt;br /&gt;
&lt;br /&gt;
A new held item, the {{DL|EV-enhancing item|Macho Brace}}, doubles the effort points gained in battle. In combination with the [[Pokérus]], a Pokémon can gain four times the normal effort points.&lt;br /&gt;
&lt;br /&gt;
In {{game|Emerald}}, certain [[Berry|Berries]] that were previously only used to make [[Pokéblock]]s can decrease certain effort values by 10 effort points (or to 100 if more than 110), while increasing the [[happiness]] of the Pokémon they were used on.&lt;br /&gt;
&lt;br /&gt;
==Generation IV==&lt;br /&gt;
[[Generation IV]]&#039;s EV system remains unchanged from [[Generation III]].&lt;br /&gt;
&lt;br /&gt;
A new series of items exist which give an additional four effort points per Pokémon defeated. Each applies the bonus to a different stat, in addition to the normal effort points gained. The bonus effort points are also doubled by the [[Pokérus]].&lt;br /&gt;

&lt;br /&gt;
A &#039;&#039;&#039;base stats structure&#039;&#039;&#039; is a 28-byte piece of data. &lt;br /&gt;
&lt;br /&gt;
Every [[Pokémon|Pokémon species]] in the [[Generation I]] {{pkmn|games}} has a 28-byte base stats structure stored in the game&#039;s ROM somewhere. It determines all information inherent to the species, such as base Attack, [[Elemental types|Types]], and [[catch rate]].&lt;br /&gt;

&lt;div&gt;==Specs==&lt;br /&gt;
&lt;br /&gt;
A &#039;&#039;&#039;base stats structure&#039;&#039;&#039; is a 28-byte piece of data. &lt;br /&gt;
&lt;br /&gt;
Every [[Pokémon|Pokémon species]] in the [[Generation I]] {{pkmn|games}} has a 28-byte base stats structure stored in the game&#039;s ROM somewhere. It determines all information inherent to the species, such as base Attack, [[Elemental types|Types]], and [[catch rate]].&lt;br /&gt;
