Barstow Community College Statistics Discussion
Question Description
I’m working on a statistics discussion question and need support to help me learn.
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¥ 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 post:
- URL for the website
- Using your own words, state the topic of the poll in a full sentence.
- State the sample size and margin of error.
- 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 9ou only need to discuss one result.
- Looking at the results with respect to the margin of error, is there a significant difference among the various responses to the question being asked? (Hint: Calculate opposing results + or – margin of error. Would they overlap? If they do, the results are NOT significantly different. If they are still far apart, then they are significantly different.)
- What role could sampling have played in determining these results?
