Following on from the last post wehre I detailed the methods of dismissal in test matches, today I’m going to keep it simple and show the distribution of runs off the bat during test matches.
One note to go with this post – it contains all balls bowled, including extras. Wides, Byes, and Leg Byes count as ‘no runs’, as do no-balls in the case of a no-ball being bowled and no further runs being scored off the bat it also counts as ‘no runs’. And in the case of a no-ball being bowled off which a batsman scores runs, then it is counted as the number of runs scored off the bat. Not exactly ideal but no-balls are proving difficult to separate thus far.
Firstly, here’s the distribution of runs off the bat by deliveries:
No runs off the bat is by far the most likely outcome – I don’t think anyone would have struggled to guess that.
Next up are singles – again, few people are going to be surprised here.
I actually expected 2’s and 4’s to be relatively closely matched but that’s not really the case.
There’s a six scored about every 40 overs – I didn’t expect them to be as common as that.
Lets quickly look at this one other way – a shot that scores two runs only occurs one quarter as often as a shot that results in a single – but it’s worth twice as many runs, so lets look at the distribution of runs scored per scoring shot.
So 3’s and 6’s are relatively rare occurrences, one of them happens on 1.3% of deliveries, but they actually provide almost 10% of the runs scored off the bat.
Boundaries contribute >50% to the runs scored in tests.
An average innings of 300 runs off the bat would constitute roughly 86 singles, 22 2’s, 5 3’s, 35 4’s, and 2 6’s, and take 94 overs.
