Problem-Solving and Data Analysis practice question
A researcher surveys a random sample of 300 adults who attend a weekly farmers' market in a city and finds that 82% cook dinner at home most nights. Which population can this result most appropriately be generalised to?
- A. Adults who attend the weekly farmers' marketCorrect
- B. All adults in the city
- C. All adults in the country
- D. All residents of the city, including children
Answer: A. Adults who attend the weekly farmers' market
The sample was drawn from market attendees, so it represents market attendees, who may cook more than the city as a whole.
Why the other answers are wrong
- B. All adults in the city
- City adults who don't attend the market were never sampled.
- C. All adults in the country
- Far beyond the sampled group.
- D. All residents of the city, including children
- Children were not surveyed, and neither were non-attendees.
