This data set is from chess tournaments, so it's predominantly games with skilled players.
- dfan 12y agoWhat I was wondering specifically was how the average rating varies by year. My hypothesis was that it has gone down over time as it has become easier for games between less skilled players to get into databases.
- rhiever 12y agoHere's a quickly made chart to show that: http://i.imgur.com/lHbVzXM.png http://i.imgur.com/lHbVzXM.png (I don't have enough games w/ Elos pre-1960 to show a reliable mean.)
- dfan 12y agoThanks. FIDE didn't implement ratings until 1970 anyway. (I'm not sure what the ratings you have for the 1960s actually are - perhaps USCF ratings.)
