ABSTRACT

Without oversimplifying, we can say that the phenomenon of sampling has been intuitive since the beginning of time, albeit in a not -so-scientific way. Your mother knows intuitively how to taste the flavor of a pot of soup. She doesn't drink the whole pot to make certain that it all tastes good. Instead, she stirs the soup, takes out a tablespoon, and tastes it. If it tastes all right, she is satisfied that the whole pot of soup has the same taste.
