We love to help, but it would be really useful if you could explain a little bit more what's confusing. For example, why you have three of them? What the boxes mean? What the numbers are and why they're different from your group sizes? All of the above? None of the above and something different?
Sorry, I should have specifed better that I wanted to know what your question was, specifically, and then offered a list of potential questions. Im still not sure what you were trying to understand, but I'll link some of the Best of answers and maybe they'll help as a starting place. Then, you can always come back if there are more things you're not sure about.
