Your explanation is very clear and easy to understand. I like how you used simple examples like colors and rankings to explain each test. You did a good job showing the differences between Pearson and Spearman. I also agree with your point about the importance of following the rules for each test. Maybe you could add a small example for the Chi-square test, like checking if boys and girls prefer different sports. That might help make it even easier to understand. Overall, great job!
