I’ve beforehand posted with regards to correlations to league success. In that submit I used NCAA volleyball information to take a look at how the most important reported associated to how a group did of their convention. As you possibly can see from the desk under, Hitting Effectivity [ (Kills-Errors)/Total Attempts ] had the best correlation to match wins, with Kills/Set not far behind. Aces/Set and Blocks/Set are decrease, and Digs/Set comes final.
In an identical timeframe, Kyle from SoloStats did his personal evaluation utilizing matches from quite a lot of ranges entered utilizing that platform. Here’s a slide from a presentation he put collectively about his observations. It’s one of some displaying a number of completely different ranges of play. You will discover the entire slide deck on the linked web page.
As you possibly can see, Kyle went a bit broader than my evaluation did. Sure, he has Aces, Kills, Blocks, and Digs per set. He additionally has errors/set for Serves, Blocks, Assaults, Digs, and Receptions (which is mainly the opposite group’s aces). He’s bought Level Scoring % (pt_sc_pct) and Sideout % (so_pct) as effectively. The previous is while you win a rally because the serving group (additionally typically known as a break level) whereas the latter is profitable the rally because the receiving group. You’ll additionally see figures for move rankings and move makes an attempt (# of instances the opposite group served). In some locations there’s additionally the variety of sideouts.
It’ll in all probability come as no shock that the scoring % figures correlate the very best to profitable. And, after all, the error tallies principally correlate negatively. The massive exception there’s service errors, which exhibits a small constructive correlation. That speaks to the requirement for aggressive serving, particularly noting that service aces ranks #3 or #4 in constructive correlation.
Associated to that, I doubt anybody’s stunned that Aces rank greater than Kills for the decrease ranges of play. We’ve all seen how a lot good serving can dominate there.
As I’ve written earlier than, I don’t put a lot inventory in the truth that blocks are likely to not correlate extremely with success. Good blocking isn’t simply (and even principally) about stuff/kill blocks. Equally, a excessive dig tally can merely imply the opposite group is attacking you a large number. Probably, that’s as a result of you possibly can’t rating in opposition to them, giving them transition swings again at you.
What I believe will shock lots of people is how low the move ranking correlates to profitable. It’s 0.2 or decrease in all 4 circumstances above. That’s as a result of an excellent move isn’t a degree scoring occasion. It solely doubtlessly leads to a degree being scored through a kill.
I encourage you to go take a look at Kyle’s evaluation. There are some fascinating takeaways.
