Law of large numbers
The larger the sample size, the more representative a sample will be of the population from which it was chosen
Eg: larger hospital: 45 babies are born each day; smaller hospital, 15 babies. Over a 1-year period, 50% boy, but exact percentage varied daily. Which hospital recorded more days on which at least 60% of babies born were boys?”
• Correct answer: Smaller hospital
• Interpretation: Subjects ignored the law of large numbers. People often assume that representativeness holds for small samples
