T20Is started on 17-Feb-2005. I was studying how batsmen (top 6) and tail-enders (8-11) perform in various formats on average since that day. I excluded number 7s from this analysis to avoid complexities.
I wanted to see strike rates and balls per dismissal for them (they are two components of average : multiplying them and dividing by 100 gives you average). Here is how the aggregate data looks.
Balls per dismissal Strike Rate
Top 6 T20 19.4 119.8
Top 6 ODI 42.2 79.5
Top 6 Test 78.0 51.2
Balls per dismissal Strike Rate
8 to 11 T20 10.1 101.5
8 to 11 ODI 18.4 75.8
8 to 11 Test 32.1 51.0
There are no surprises in the balls per dismissal data. Tail-enders get dismissed much more often than batsmen. Also, players get dismissed more often in shorter formats for obvious reasons. They also score faster in T0Is than in ODIs, and much faster than in Tests.
However, if you look at how the strike rates compare between batsmen and tail-enders, it gets a little more interesting. While the difference is considerable for T20Is (120 versus 102), in ODIs the difference is not so pronounced (80 versus 76). And in test matches there is no difference. Overall, the difference in SRs (0-20%, depending on format) is nowhere comparable to the difference in balls per dismissal (90-150%, depending on format). Since there are no differences in strike rates for tests, can we attribute at least a part of the difference for limited overs cricket to the fact that tail-enders don't get to bat in power-plays? Can we say that the boundary-hitting ability is not drastically different between batsmen and tail-enders? ...and the real difference lies in how often they get dismissed?
Also, overall what does the above data tell you? Do you have any other observations?
Edit: In fact, if you remove 1 from balls faced per dismissal, the difference in scoring rate becomes more miniscule. For example, if we say that tail-enders get dismissed once in every 10.1 balls that means 1 of those 10.1 deliveries is being consumed for getting out. So, he basically scores all his runs in 9.1 deliveries.
