the quick analysis on the 104th summer Koshien tournament

Today’s topic is a quick analysis of the 104th summer Koshien tournament in Japanese high school baseball.
 
Slide 1;
This graph shows the number of participating schools and representative schools in each tournament.The participants have been deceased recently. Unfortunately, the 102nd tournament was canceled due to the COVID-19 pandemic.It was the 3rd time to be canceled after the rice riot in 1918 and the Pacific War in 1941 in Japanese high school baseball history. The current 3rd-year students entered a high school in 2020 when the COVID-19 began. They must have experienced many difficulties. 

Slide 2;
This graph shows the winning percentage and the number of victories per prefecture.This line chart shows the winning percentage.
And this line chart shows the percentage to advance the quarterfinals. Can you imagine the top 3 prefectures with high winning rates?
The Top is Osaka, the 2nd is Ehime, and the 3rd is Kanagawa. 

Slide 3;
This graph is to analyze the relationship between the number of participating teams and the winning rate in the Summer Koshien per prefecture.The vertical axis is the winning rate, and the horizontal axis is the number of participating teams.
I am plotting both data on the graph. I think that many high school baseball fans misunderstand the relationship between the two data.The correlation coefficient is 0.3522 which is not a strong correlation.
