Correlation between Math and CP skill results
By SlavicG, 2 years ago, In English

Hello Codeforces!

Here are the results of the poll I made a week ago!

Because of the small sample size of 500 responses and a lot of other factors I am pretty sure the results aren't the most accurate, so take them with a grain of salt.

Anyway, let's start with the direct correlation table, for each of these items in the table, you can see the dependency level on the items represented as numbers between in the range [-1, 1], -1 meaning complete inverse correlation and 1 complete correlation, as the absolute value decreases the correlation decreases as well.

As we can see, there isn't that strong of a correlation, the strongest for rating being the people who practiced for math Olympiads and participated in national ones.

Now, here are results individual for rating ranges:

0-999
1000-1199
1200-1399
1400-1599
1600-1750
1751-1899
1900-2099
2100-2199
2200-2399
2400-2599
2600-2999
3000+

Even though there isn't that much of a noticeable correlation we can notice that the amount of participants and medalists in higher rated users is higher than the lower rated users. Same goes for the percentage of people that prepared for Olympiads.

But, what do others think? It turns out most think their previous math experience helped them achieve their current rating

Here you can access the document with all the data, in case anyone is curious about some more details I might have missed.

Thank you for reading the blog and answering to the poll!

I highly doubt that the responses for LGMs' math level are completely accurate and serious -- most of them say that their math is "primary school level" (4 out of 7)...

    And it's also terribly weird how two of them got some sort of medal in "International Math Olympiads", but at most one of these got a medal in "National Math Olympiads" :))
