　　Read the following SAT test question and then click on a button to select your answer.

　　A consumer-monitoring service wants to determine television viewing habits among 18-to 29-year-olds in a particular city. Which of the following survey methods is most likely to produce valid results?

　　A.Select a random sample of 1000 18- to 29-year-olds in that city.

　　B.Select a random sample of 1000 18- to 29-year-olds in that city who attended a computer camp when they were in high school.

　　C.Select a random sample of 1000 18- to 29-year-olds in that city who played a varsity sport in high school.

　　D.Select a random sample of 1000 18- to 29-year-olds in that city who played chess in high school.

　　答案：A

　　解析：

　　Choice A is correct. In order to produce unbiased, valid data, the sample should be randomly selected and be representative of the entire population of interest. In this case, an appropriately conducted survey should give each consumer aged 18 to 29 years in the city an equal chance of being surveyed.

　　The choices that involve a particular high school, the chess team, and computer campers would not be representative of the entire population of 18- to 29-year-olds in the city.
