Question

Juanita is conducting survey research for the Colgate-Palmolive Company. The company recently sent several cases of personal-sized toothpaste to Dr. Yankum as a part of a promotion. Juanita is surveying patients as they leave Dr. Yankum's office to ask if the dentist gave them any hygiene items to continue quality dental care. Juanita has discovered that practically every patient received Colgate and has concluded in her report that dentists prefer Colgate toothpaste over other brands. What flaw exists in Juanita's research?

Answer 1

Answer:

She is using a biased sample for her data collection

Explanation:

Juanita should have gone across different sections to collect her data in order to have a more representating sample but the samples she used is biased because she was generalizing her study based on only one dentist that she got to study her patient whereas the doctor has gotten some toothpaste from the company.
