In our school, students with different Math ability are divided into different sets: A, B, C, D, E, F & G. We did a Sudoku test among our classmates to find out whether their Math ability will affect their level of playing Sudoku. The results are as follows:
At first, we thought that students with better Math ability will have better results when doing Sudoku. But it turned out that there is not really a relationship between the Math ability and the Sudoku level.
Then, we did another survey to see if the playing frequency of students will affect their Sudoku results. There are four main groups of playing frequency: Always and very often, often, sometimes, never. The results are as follows:
We found that students who play more get better results. That means the more you play, the better you will be. "Practise makese Perfect!"
