Question: several years ago pepsi decided that cokes lead in toronto...

Question details

Several years ago, Pepsi decided that Coke's lead in Toronto was no longer acceptable so they decided to conduct a taste preference study. Participants were chosen from Coke drinkers in the Greater Toronto Area and they were asked whether they preferred the glass of Coke or glass of Pepsi.  Experimenters prepared the drinks, labeled the glasses and recorded participants’ choice. To help prevent any bias, the glasses were not labeled "Coke" or "Pepsi".  Instead, the Coke glass was marked with an "O" and the Pepsi glass marked with a "T".  All participants sampled the "T" glass followed by the “O” glass. Results showed that over half of the subjects chose Pepsi over Coke, and researchers concluded that Canadians preferred Pepsi over Coke.
