Question
A polling firm wants to know which candidate is likely to win the presidential election. The major-party candidates are Republican Dewey Cheatum and Democrat Ann Howe. The pollsters set up an Internet site and ask site visitors to indicate their preferred choice. The results: After months of polling and a sample of hundreds of thousands of individuals, Republican Cheatum held a huge edge. The only problem: On Election Day, Howe won handily. There was obviously a big difference between the preference of the population about which the polling firm wanted to draw inferences and the preference of the sample they obtained.
A. What was the population the firm was interested in?
B. Describe two reasons why the sampling technique was a poor one.
C. Internet polls like the one described here almost always find a preference for the Republican candidate over the Democratic candidate. Why do you suppose this is?
Explanation / Answer
a)The firm was interested in the individuals who belong to that particular region where election is conducting and also the individual who have right to vote i.e., above 18.
b)
i)They just created a site where people can show their interest towards two parties but this site can be used by different individual who do not have right to vote or may does not belong to particular place.
ii)All individuals may cannot use internet.
c)This might be probably because republican supporters are using more internet over democratic supporters.
