Heading 1 Heading 2 Title Subtitle Paragraph Styles The San Francisco Chronicle reported on a survey of top high-school students in the U.S. According to the survey, 1. Cheating is pervasive. Nearly 80% admitted some dishonesty, such as copying someone's' homework or cheating on an exam. The survey was sent last spring to 5,000 of the nearly 700,000 high achievers included in the 1993 edition of Who's Who among American high school students. The results were based on the 1,957 completed surveys that were returned. "The survey does not pretend to be representative of all teenagers." Said who's who spokesman Andrew Weinstein. Students are listed in who's who if they are nominated by their teachers or guidance counselors. Ninety eight percent of them go on to college. Why isn't the survey "representative of all teenagers"? Is the survey representative "of the nearly 700,000 high achievers included in the 1993 edition of Who's Who among American High School Students"? Answer yes or no, and explain briefly a. b.

Explanation / Answer

a) The survey is not representative of all the teenagers because the survey letters where sent only to the 700000 students listed in the Who's Who magazine. These students are supposed to be the high achievers as per the input from teachers and guidance counselors.

The students who are not listed also should come under the purview of the survey as the survey questions are applicable to them also.

Thus, it is not a representative sample of all teenagers.

b) Yes.

The survey letter was sent to all the 700000 students and the students who would have returned back the survey are completely random. The 700000 students are supposed to be high achievers and without any particular distinctions.
