An examination of 4.4 million games listed from op.gg shows that champions with higher KDA Ratios reach the victory screen more often than those champions with lower KDA Ratios.

Also of note, the median of champion win rates is 46.25% rather than 50%. https://docs.google.com/spreadsheets/d/11yGk3qnPmm63YtV3FkvovmKGrECks1FQnzVYUdPW8ZY/edit?usp=sharing
Reikken2 votesIt's not surprising that the median win rate is below 50%. The mean win rate could still be 50%, but the higher win rate champions get played a lot more than lower ones, so the positive win rates are weighted much more heavily.
GaleWinUnleashed1 votesThe mean win-rate is exactly 50%. That's how mean works =P

GaleWinUnleashed1 votesOf course. The majority of champions have a sub-50 winrate, but it's balanced out by some exceptionally high winrates that bring the mean to exactly 50%.
Marshbouy1 votesNext up water is wet. (btw it literally has to be 50% win rate. Champion.gg misses games somtimes)

The outcome is indeed mind-boggling. Great science often starts with "hmm, that's odd..."
The number of games played by each champion, divided by the total games listed gives their proportion of participation in the dataset.
Marshbouy1 votesIt's pretty weird, not going to lie. but the math makes it so that it should be 50%, so it's either the math is flawed. there are games where both sides lose. champion.gg doesn't record all the games. Using logic you would assume it's champion.ggs fault.
Romans VI XXIII3 votesincorrect, the Win rate of GAMES is 50%
This is a median win rate for CHAMPIONS, which does not have to be 50%.
Example:
Game 1 A B C D E vs F G H I J Team 1 wins
Game 2 A F B G H vs K L M N O Team 2 wins
A: 50% 1/2 B: 50% 1/2 C: 100% 1/1 D: 100% 1/1 E: 100% 1/1 F: 0% 0/2 G: 0% 0/2 H: 0% 0/2 I: 0% 0/1 J: 0% 0/1 K: 100% 1/1 L: 100% 1/1 M: 100% 1/1 N: 100% 1/1 O: 100% 1/1
Count: 15 Sum: 900 Mean: 60 Median: 100 Mode: 100
Since not every champion can be played in every game neither the mean or median will ever be truly 50% until every champion is evenly played.
Marshbouy1 votesI see. Ty for the explanation
Maximum Morde1 votesThat isn't unexpected. Champions that have lower kda give the enemy team more gold, which tends to lead to the enemy winning, where high kda is an indicator of your own teams gold.

An empty lane is winnable by my dog...
ScissorsNstuff1 votesI think this needs to be done based off specific champs
ScissorsNstuff1 votesaccording to op.gg something like 95% of champs have less than a 50% winrate kek

XD
This statement that 95% of champions lose could be true (unlikely) if the remaining 5% of champions won the balance. Do the remaining 5% of champions appear as the winning side to the 95%'s losses?
Most websites listing champion win rates declare percentage wins much closer to 50%.
