Cool - thanks. Seems like if you remove the outliers (Souths, Brisbane and David Fifita) there is a small trend of scoring down the left. Would also be interesting to see that without tries from kicks and intercepts.
I guess I’ll have to add another column to my spreadsheet for whether the edges played left or right.
I look forward to your left right edges stats and your try score location (accounting for try type)!
Teams that score more on right than left are Broncos (+29%), Sea Eagles (+3%), Dragons (+15%), Roosters (+7%), Warriors (+1%), Tigers (+1%).
So 6/16 score more on right than left but only two I would call statistically significant (assuming >+10% is relevant).
Meanwhile on left Raiders, Titans, Knights, Cowboys, Eels, Rabbitohs all score more than +10% on the left vs the right.
(Leaves Dogs, Sharks, Storm as having statistically insignificant leans to the left)
Titans are a confusing one... score vast majority (44%) on left, 31% middle and 25% right, but David Fifita plays right edge.
Not an exact science by any means but he scored 17 tries last season and they only scored 27/108 on right edge. TBH most of the others on their right were probably because of him too...
Now, because I've got too caught up in this, last seasons ladder
(in brackets based off if we call just 5% statistically relevant)
Storm - balanced (balanced)
Panthers - balanced (left)
Rabbitohs - left skewed (left)
Sea Eagles - balanced (balanced)
Roosters - balanced (right)
Eels - left skewed (left)
Knights - left skewed (left)
Titans - left skewed (left)
Sharks - balanced (balanced)
Raiders - left skewed (left)
Dragons - right skewed (right)
Warriors - balanced (balanced)
Wests Tigers - balanced (balanced)
Broncos - right skewed (right)
Cowboys - balanced (left)
Bulldogs - balanced (balanced)
To include the middle, teams that score 25% or more of tries in the middle finished 1st, 4th, 6th, 8th, 10th, 11th, 12th, 16th so being good at scoring in the middle or not isn't seemingly a great indicator of success.
