What is the percentage of goals scored on penalty kicks?
I am creating a database of recent results from the top 5
divisions of English football. I have a complete record for each of
those divisions for the current season plus the whole of last
season for the Premiership. Within that sample, 173 out of 3528 are
penalties. So about 1 in 20? I'll have the last 5 years of football
in the database soon so if you want a more complete answer contact
me through my bluebones.net website. Just out of interest, 53 out
of 3528 are own goals. -- Update: I now have data on 33,671 English
league and conference goals from the last 5 years. 1569 of 33,700
are penalties. 448 are own goals.
