Did-Not-Participate-1976-to-2008

Starting from the original dataset (Summer-Olympics-medals-1976-to-2008).
I wanted to find the average number of medals won for each country, i then noticed however that many countries didn't participate in all the olympics, counting their non-presence as 0 medals won would unfairly worsen their average.

And so I took all the countries that appeared in the original dataset and checked on Wikipedia which olympics they didn't participate.

I then manually created a csv.
