Super Sample If a researcher aims to understand American attitudes about supersize soda bans, she would be foolish to limit her study to residents of New York City. Michael Bloomberg, the mayor of the Big Apple, called for a ban on the sale of supersized sugary drinks in 2012. The controversial law probably affected attitudes about the issue, even though the law was subsequently struck down by a judge. Thus, the people of New York City do not constitute a representative sample.
