• Win Rate

  The statistical chance of winning a match when playing as the selected champion in the selected game mode, with a custom loadout.

• Margin of Error

  The margin in which the actual win rate of the champion is, with a 95% certainty. A smaller Margin of Error means a more accurate win rate. Win rate is not shown for cards with a Margin of Error above 5%, as these are bad representations.

• Sample Matches

  The sample size of the data, which is the amount of found matches with the selected champion and game mode combination. A higher sample size improves the quality of the data, and data is derived from matches found over several days.

• Popularity

  The percentage of matches where the champion had the given card, of matches where the champion did not use basic loadout.

• Acknowledgments

  The win rate of a card can become skewed, if favored by either players of above or below average skill level, e.g. a card favored by above average players will do better in the statistics, because its win rate is influenced by the average success of its major audience. Matches where the champion has the basic loadout are excluded, in order to block the influence this could have on cards in these loadouts.

  Items bought late in the game have a tendency to have a slightly higher win rate than is representative for those items. This is due to you getting ahead of your opponent is making you increasingly more likely to win, while falling behind is making you increasingly more likely to lose. However, the influence of these factors are minuscule.
