A newspaper reporter wants to know how popular the hobby of bird watching is in the city. He asked people at the local bird refuge if they watched birds as a hobby. Which of the following best explains whether the reporter's data is valid or not?
A. The data is valid for the entire city because the bird refuge is located in the city.
B. The data is not valid for the entire city because people can have more than one hobby.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
D. The data is valid for the entire city because a bird refuge is a good place to find people who like to watch birds.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
Explanation: While the reporter may have collected data from people at the local bird refuge, it cannot be generalized to the entire city. People who visit a bird refuge are more likely to be bird watchers or have an interest in bird watching. This sample does not necessarily represent the entire population of the city, as there may be people who watch birds as a hobby but do not visit the bird refuge. Therefore, the data collected at the bird refuge is not representative of the entire city's population and cannot be considered valid for the whole city.
