In the book Scorecasting, we learn that ‘‘Across 43 professional soccer leagues in 24 different countries spanning Europe, South America, Asia, Africa, Australia, and the United States (covering more than 66,000 games), the home field advantage [percent of games won by the home team] in soccer worldwide is 62.4%.” Is this a population or a sample? What are the cases and approximately how many are there? What is the variable and is it categorical or quantitative? What is the relevant statistic, including correct notation?
