Statistician: A financial magazine claimed that its survey of its subscribers showed that North Americans are more concerned about their personal finances than about politics. One question was: тАЬWhich do you think about more: politics or the joy of earning money?тАЭ This question is clearly biased. Also, the readers of the magazine are a self-selecting sample. Thus, there is reason to be skeptical about the conclusion drawn in the magazineтАЩs survey.
Each of the following, if true, would strengthen the statisticianтАЩs argument EXCEPT:
(A) The credibility of the magazine has been called into question on a number of occasions.
(B) The conclusions drawn in most magazine surveys have eventually been disproved.
(C) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.
(D) There is reason to be skeptical about the results of surveys that are biased and unrepresentative.
(E) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues.
the statisticianтАЩs argument is that the question is clearly biased, that the readers of the magazine are a self-selecting sample and therefore that there is reason to be skeptical about the conclusion drawn in the magazineтАЩs survey.
His argument is not about the result but about the way the data have been collected.
Moreover in E, you don't know clearly the result, you just know americans are interested by politics, finances and social issues.
