Question description

1.  Suppose you are designing and conducting a poll to see which of the presidential candidates are popular in your area. Discuss the following: the population that you are trying to predict, where and how are you selecting your sample, what sampling method would you use, how would you assure that you are selecting a representative sample, and show an example of how you would present your data. So you should copy your graph to a Word Document and attach it.

2.  When the results of a survey or poll are published, the sample size and the margin of error are both given. For example: 1000 voters were surveyed and 39±2% of the voters agree with the president. In this example N=1000 and the margin of error (MoE) is 2%.

This website lists several public opinion polls. Search the site and find a poll where the sample size and margin of error are given. Try to find a poll dealing with a topic in your profession or one in which you are really interested.


Determine the following information for the selected poll results and include in your initial post:

A.  URL for the website

B.  Using your own words, state the topic of the poll in a full sentence.

C.  State the sample size and margin of error.

D.  Interpret the results of your poll using your own words and full sentences. Note: Depending on the question asked, your poll may have more than one poll result – you only need to discuss one result.

E.  Looking at the results with respect to the margin of error, do you think there is a significant difference in the responses to the different questions being asked?

F.  What role could sampling have played in determining these results?
