Use the guidelines to evaluate the study. Discuss flaws that you see in the study. A documentary which appeared on a TV station owned by a large biotech company announced that 77% of Americans are in favor of genetically modified foods. The researcher for the documentary had conducted a telephone poll of 200 people selected randomly from the phone book. Each person in the sample had been asked "Are you in favor of increasing the production of genetically modified foods in order to increase the world food supply?"

What will be an ideal response?


The source is biased. Since the TV station is owned by biotech company, the producers of the documentary may be biased toward making favorable statements about genetically modified food. 
The wording of the question is not neutral and will influence the answers. 
There is selection bias as the poll is restricted to those who own a phone
