Scottish Premiership - Assessing Under/Over Performance
Data is becoming more and more available in football and is now largely accessible to the average fan. However, as is clear to most people, not all data is useful.
Shot data is a prime example of this.
The standard way of recording shots on target or off target can often give a misleading view of what happened during a game, particularly if you haven’t seen the shots in question.
In StrataBet, we don’t just record shots on/off target. We record the quality of chances.

This is simple, but extremely effective.
Rich’s blog gave detail on the conversion rates of these chances. It showed a linear trend that provides an excellent basis to investigate which teams are over-performing or under-performing.
This season I have been working on the Scottish Premiership, so have taken the chance to look at which teams have been “good” and which have been “lucky”.
