How did everyone else do?
"What about the distribution of all the other 2114 students that weren't in the top 100?" I hear you cry. Don't worry, we've got you covered.
Around 40% of students only submitted one answer and the number of answers submitted dropped off to form a nice looking exponential decay curve in the chart below. It's pure maths wrapped in statistics and then shipped with puzzles!

Correct Answers All Submitted Answers
1 or more 72.5% 1 or more 100.0%
2 or more 42.1% 2 or more 59.7%
5 or more 14.2% 5 or more 27.4%
10 or more 3.6% 10 or more 7.9%
20 or more 0.5% 20 or more 0.9%
All 31 Nobody All 31 0.1%


What should you call your child if you want them to be a great puzzler?
Because... do we really need a reason for doing extra statistics for fun?
With Jack the most common forename and Tan the most common surname it would appear our typical puzzler is called Jack Tan (and we did have one Jack Tan enter the competition).

Surname Number of students with that surname Forename Number of students with that forename
Tan 59 Jack 15
Lee 55 James 12
Lim 51 Ethan 12
Wong 26 Sam 11
Ng 25 Daniel 11
Ong 19 Ryan 10
Kim 18 Joshua 10
Goh 16 Sophie 9
Yap 13 George 9
Chan 13 Emma 9

However, when we look at the number of answers by each of the names above it would appear that the Jacks and Tans are not the most productive students and in fact it's the Ryans and the Lees that submitted the most answers (helped by Ryan Lee - third in the world last year).

Surname Answers by people with that surname Forename Answers by people with that forename
Lee 316 Ryan 65
Tan 254 James 52
Lim 186 Ashley 51
Wong 136 Ethan 39
Ng 128 Sean 39

Then again, perhaps it's unfair to measure success purely on the number of submissions because it doesn't tell us about the quality of the answers. Below we can see that when we look at correct answers submitted the top 5 surnames don't change at all. However, we get some girls (Ashley and Angel) both pop up in the top 5 forenames.

Surname Correct answers by people with that surname % correct answers by people with that surname Forename Correct answers by people with that forename % correct answers by people with that forename
Lee 241 76.3% Ryan 57 87.7%
Tan 173 68.1% Ashley 41 80.4%
Lim 117 62.9% James 31 59.6%
Wong 93 68.4% Sean 30 76.9%
Ng 90 70.3% Angel 30 96.8%

However, if you think about this some more (and sadly, I really have) then perhaps it's best if we looked at the average number of answers and correct answers per name. The tables below are only for those names of which there are at least 5 contributing students to make outliers less influential.
I'll leave you to decide what the best measure for success for a name is as to me it suddenly it appears that it's very difficult to pick the most successful surname. It is definitely Ryan all the way for the most successful forename last year.
